OpenVPN is an excellent open-source VPN that lets us browse the internet anonymously. But, like other VPN apps, it also sometimes faces issues in working. For instance, some users in the online forums mentioned that the OpenVPN isn’t working properly on their Windows 11 PC.
If that’s the same with the OpenVPN app on your Windows 11 PC, then read this in-depth fixes guide until the end. Here in this guide, we’ll share some working fixes to fix OpenVPN not working in Windows 11. Let’s get into and fix this issue with ease.
Why Is OpenVPN Not Working in Windows 11?
Various reasons could make the OpenVPN program inoperable on your Windows 11 computer. Below, we’ll mention the most prevalent reasons for OpenVPN not working in Windows 11. So, check all the possible reasons for the ill-functioning OpenVPN app below:
- Interruption by Windows Defender Firewall
- Bugs and Glitches in the PC
- Lack of Administrative Rights
- Misconfigured OpenVPN Config File
- Azure VM Isn’t Correctly Configured
- DHCP Client Service Isn’t Working
- Third-Party Antivirus Programs
- Corrupted DNS Cache
- Corrupted Temporary Files
Fix OpenVPN Not Working in Windows 11
In this section, we’ll share the most working workarounds to fix OpenVPN not working in Windows 11. So try all of them one by one and check what works for you and what doesn’t:
1. Restart Your PC
One of the most effective yet easy-to-apply workarounds in this troubleshooting guide is to restart the affected PC. Doing so will fix all the problems that may be causing this issue with it. To know if it fixes the issue for you, follow the below steps to restart your Windows 11 PC:
1. Use the Alt + F4 keyboard shortcut to open the Shut Down Windows prompt on your PC.
2. In the Shut Down Windows prompt, pick the Restart option from the menu and hit Enter.
3. Once done, your PC or laptop will restart, and once it’s started, check if the OpenVPN is working.
2. Run OpenVPN as an Administrator
It may be possible that the OpenVPN isn’t opening or launching on your Windows 11 PC due to a lack of administrative rights. We suggest you run the OpenVPN program with admin privileges to check the same. We’ve mentioned the steps to do so, so follow them:
1. Open the Windows Search Box on your Windows 11 PC by pressing the Windows key.
2. In the Windows Search Box, type OpenVPN and choose Run as administrator from it.
3. In the User Action Control window, click the Yes button to open it with administrative rights.
Another way to launch OpenVPN with admin rights is from the context menu. To open it from the contextual menu, right-click the app’s shortcut and select Run as administrator from it. Then, click the Yes button in the UAC window to launch it with admin rights on your PC.
3. Disable Windows Defender Firewall
A set of users in the online forums mentioned that the Windows 11 PC’s built-in Windows firewall could also be the one stopping the OpenVPN program from launching or working on it. Thus, to check whether it’s true, consider turning off the integrated firewall on your Windows 11 computer. You can check the below-mentioned prompts to know how to do so:
1. Press the Windows key to open Windows Search Box, and type Firewall & network protection in it.
2. Choose the Firewall & network protection option from the search to open the firewall settings.
3. In the Firewall & network protection window, select Private network and disable the toggle on the next screen.
4. Once done, go back to the previous window, and this time, select the Public network option.
5. In the Public network window, turn off the toggle and exit the window to see the change.
4. Whitelist OpenVPN and OpenVPN GUI
If you don’t want to disable your PC’s integrated firewall due to security reasons, we suggest you whitelist OpenVPN Connect and OpenVPN GUI through it. It’ll allow them to work properly without any issues. So, learn to do the same by following the below-listed steps:
1. Open the Firewall & network protection app on your Windows 11 PC and click the below option:
Allow an app through firewall
2. On the next screen, click the Change settings button and then Allow another app… button.
3. In the Add an app window, click Browse… and move to the location where the VPN is saved.
4. Choose the app, click the Open button, and then select the Add button to import the location.
5. Tick both checkboxes next to it in the box and click OK at the bottom to save the change.
6. After doing so, restart your Windows PC and check whether the OpenVPN is working now.
5. Edit the OpenVPN Config File
Some users in the online forums said that making some necessary changes to the OpenVPN configuration file fixed the issue for them. Thus, we suggest you do the same and check if it works for you. You can need to enter the below lines in your config file:
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 208.67.222.222"
push "dhcp-option DNS 208.67.220.220"
6. Force Close & Restart OpenVPN
It may be possible that your OpenVPN app is facing some issues in working, which is why the OpenVPN not working issue is appearing on your Windows 11 PC. In that case, force close and restart OpenVPN on your PC. You can follow the below steps to try out the same:
1. Press Ctrl + Shift + Esc to open the Task Manager program on your Windows 11 PC or laptop.
2. In the Task Manager window, search for the OpenVPN Connect app and right-click on it.
3. Right-click the OpenVPN Connect process and choose the End task option from the menu.
4. In the end, reopen the OpenVPN Connect and check whether it opens or works well now.
7. Make Sure Your Azure VM Is Correctly Configured
Some users in the online forums said that they’re only facing issues with Azure VM. If that’s the same with you, you need to make sure that your Azure VM is properly working now. We hope you find and fix the OpenVPN not working issue on your Windows 11 PC or laptop.
8. Ensure the DHCP Client Service Is Running
The DHCP Client service is an integral Windows service that registers and updates IP addresses and DNS records for the PC. If this service is stopped, this computer will not receive dynamic IP addresses and DNS updates.
Also, components that depend on it will fail to work. So, this could be the same in your case. So, make sure that the DHCP Client service is working properly. You can check the same by following the below process:
1. Press Windows + R to open the Run program and type Services.msc in its search box.
2. In the Services window, look for the DHCP Client service, choose it, and right-click on it.
3. From the right-click menu, choose the Properties option and ensure Stopped is written next to Service status:. If there’s nothing mentioned like that, click the Start button to restart it. In case it was already enabled, choose the Stop button and then Start to restart it.
9. Uninstall Third-party Antivirus
If you’re using a third-party antivirus app on your Windows 11 PC, it could be possible that it’s causing this issue, as sometimes, they prevent the VPNs from working due to security concerns.
So, we suggest you uninstall the third-party antivirus program from your PC. You can check the below-mentioned steps to know how to uninstall apps in Windows 11:
1. Open the Windows Search Box by pressing the Windows key and enter the name in it.
2. Select the Uninstall option from the Windows search results to open the Installed apps window.
3. On the next screen, search the antivirus app you want to delete from your Windows 11 PC.
4. Click the three dots (…) next to it, and from the dropdown menu, choose the Uninstall option.
5. In the new prompt, choose the Uninstall button and let the app uninstall from your device.
After removing the antivirus app from your device, check if the OpenVPN app is working now.
10. Clean the Temp Folder
Some users in the OpenVPN forum mentioned that cleaning the Temp folder of the user in which the OpenVPN Connect App is not starting/opening can also fix the OpenVPN not working issue. Considering this, we suggest you also do the same and check whether it works. We’ve mentioned the instructions to delete the Temp folder from your computer below:
1. Press the Windows + R hotkey to open the Run utility and type %temp% in the search field.
2. In the Temp folder, use the Ctrl + A keyboard shortcut to select all the files and folders in it.
3. Select the Bin icon in the top navigation menu to delete the selected folders from the folder.
4. Once done, exit the File Explorer window on your PC and restart your Windows 11 PC.
11. Flush Your DNS Cache
One way to resolve OpenVPN-related issues is to clear the system’s DNS cache, as it could be possible that it has been corrupted. Thus, to check this, we suggest flushing your PC’s DNS cache. To know how to clear the DNS cache in Windows 11, check the below steps:
1. In the search, type Command Prompt, and then select it from the search results with admin rights.
2. In the Command Prompt utility, run the below-mentioned commands and press the Enter key:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
3. After running the above command, confirm if OpenVPN is working on your Windows PC.
12. Update Windows
It may be possible that the OpenVPN not working is appearing because of some bugs and glitches in the PC. In that case, we suggest you update your Windows 11 PC and see if the new updates fix these problems. Below are the right steps to update Windows 11:
1. Launch the Settings app on your Windows computer and choose Windows Update at the top.
2. In the Windows Update window, choose the Check for updates button to search for updates.
3. If you find new updates to install after clicking Check for updates, click Download & install next to them to do so. Otherwise, click Download & install all to install all at once.
13. Reinstall OpenVPN
If none of the above-mentioned workarounds help you get rid of the OpenVPN not working issue in Windows 11 until now, consider reinstalling the OpenVPN app on your PC. Doing so will eliminate all the issues and, hopefully, also resolve the issues with it. You can follow the below-mentioned prompts to reinstall the OpenVPN app on your PC:
1. Get the Windows Search Box on your Windows 11 PC and type OpenVPN Connect in it.
2. From the search results, choose the Uninstall button and search the OpenVPN Connect app.
3. Click the three dots (…) next to it, and choose the Uninstall button from the dropdown menu.
4. Click the Uninstall button in the new prompt to delete the program from your Windows PC.
5. Once you’ve uninstalled it, click here to get the OpenVPN Connect installer on your PC.
14. Roll Back to Windows 10
For some users, the issue with OpenVPN started appearing after upgrading the Windows 10 PC to Windows 11. If that’s the same with you, consider rolling it back to Windows 10, as doing so will fix all the issues that are causing OpenVPN not working in Windows 11. So, follow the below-mentioned steps to easily revert your Windows 11 PC to Windows 10:
1. Launch the Settings app on your Windows 11 PC and head to the Recovery section of it.
2. In the Recovery window, click the Go back button next to Go Back under Recovery options.
3. After clicking the respective button, follow the on-screen prompts to revert to Windows 10.
15. Submit a Support Ticket to OpenVPN Support
If you still can’t use the OpenVPN Connect program on your Windows 11 PC, you should submit a support ticket to its support. Hopefully, they’ll provide you with some working workarounds to eliminate all the issues with the OpenVPN Connect app on your Windows 11 PC. Check the below-mentioned steps to know how to contact the OpenVPN support:
1. Click here to visit the OpenVPN official site in your browser and click Support at the top.
2. Click the Submit A Support Ticket button and choose the appropriate option from the menu.
3. Enter your email address in the Your email address text box and then enter the subject.
4. Choose the right option from the OpenVPN Product (Required) and Server Instance Type menu.
5. Enter the OpenVPN Connect client version and then choose the OS you’re using the VPN on.
6. Write a detailed description in the Detailed Description (Required) box and fill in other fields.
7. Once done, click the Submit button and then wait for the support to revert back with a fix.

Windows11 connects but will not pass traffic
Hi-
I’m First time poster/asker here.
Am using Openvpn Connect (version 3.3.6 *2752*)
On clean Windows 11 pro install which is fully up to date.
Along with PFSense OpenVPN server.
Server is remote and we are accessing a LAN behind it at the remote location.
Client is local(here) and is running on Windows 11 and is behind a PFSense NAT device here.
The client connects to the server without any issue but will not pass any traffic right after connecting consistently and repeatably.
If I reboot the Windows 11 computer it always seems to work just fine if I connect the vpn client to the vpn server right after rebooting.
It also seems to work fine after that until some time period passes or I reboot again.
I can recreate the problem by rebooting and not using the vpn client immediately after reboot.
If I reboot and then try to use the vpn client 1-2 hours after reboot the issue happens where it connects but cannot pass any traffic.
And the only way I can get it to work is to reboot the computer and connect immediately after rebooting.
Windows firewall is turned off on the computer, and there are no power save or sleep features turned on.
The PC does not go to sleep ever. nor does it log off or turn on a screen saver.
I do not have this problem in Windows 10 booted up on the same computer same IP same scenario.
I’ve made my network config as simple as possible, single ethernet and the TAP-Windows adaptor created by openvpn connect.
1. Is this a known issue? I’m looking around for anything like this.
2. Also looking for hints on troubleshooting this further.
I will keep looking and thanks!

Disconnected and waited about an hour, reconnected and does not pass any traffic at all.
reconnected several times nogo.
Only way to get it to connect again is to reboot and connect after freshly rebooting.
I’ll try a few other things restarting services, disabling/enabling interfaces etc. to see if I can narrow it down any further than an entire reboot.

disabling and re-enabling the ethernet interface on the client PC does not make it work.
Enabling and disabling the Windows firewall does not make it work.
So far only rebooting it makes it work.
I cannot ping or reach any remote host on the server’s network, nor can I reach the far end gateway on the IPSEC
tunnel that is created as a route entry by openVPN when it is not working.
I’m going to reboot and verify that the remote gateway that is setup in the route tables does not change while it is working and is reachable.
I suspect it will look the same while it is working after the reboot.
And the specific route that we are using is of course:

Update:
With the tunnel connection up and waiting what seems to be about ten minutes, it eventually starts workign and passing traffic.
You have to wait *at least 5 minutes* before it starts working.
No change in routing table and .13 is also pingable.
I do not experience this long wait if I reboot the machine and connect.
It always works right away after a reboot of the client PC.
Casual remindter that the client always connects instantly witout issues.
It does not pass any traffic when it’s not working.
There is no indication of any problems/issues serverside or client side.
And this problem does not happen with Windows 10. on the same computer in the same scenario.

Nothing changes or is different in the route table when it is working vs. not working.
Route table has some extra entries (not sure if they are other clients) or ?
.13 is not pingable when it’s working either, (shown as the gateway to 10.74.74.0/24)
My client is .14
.12 and .15 also show up in the route table when the client is actively connected.
10.74.74.1 is the far end openvpn server and is reachable when it is working.
10.74.74.0 255.255.255.0 44.103.31.13 44.103.31.14 257
44.103.31.1 255.255.255.255 44.103.31.13 44.103.31.14 257
44.103.31.12 255.255.255.252 On-link 44.103.31.14 257
44.103.31.14 255.255.255.255 On-link 44.103.31.14 257
44.103.31.15 255.255.255.255 On-link 44.103.31.14 257
Please do not get confused by the address space being used internally.
This is not a factor in the issue we are having
And is a bit beyond the scope of this discussion why it is being used.
I know some people will be curious about this and will not be able to resist asking or pointing it out.

I also logged into the local pfsense firewall NAT providing device and cleared any lingering states to the remote openvpn server,
Just as an additional troubleshooting measure.
So that establishing a new connection was assured to create a set of fresh new states and assure me that the old lingering states were not somehow
being re-used, as PFSense does some nifty port randomizations on the source port coming from the internal host on and outbound connection by default.
This was not the issue either.
Getting the same result…
Have to wait 5-10 minutes with the client connection up before any traffic starts to pass from the PC here to the far end LAN host.
I’m just testing with a Ping test and an SSH session to a remote host when the connection is working.

Did further analysis:
Determined for sure it was not a multi session issue or port randomization issue by configuring outbound static port for this type of traffic (UDP1194)
and watched at the far end server to be assured that there was no issue with outbound port changing in transit or in stale NAT states.
Friendly Reminder: this is not happening with Windows 10 and openvpn client.
Also confirmed that settings on server allow multiple sessions from same user/IP address without issue.
Update: the delay is NOT 5-10 minutes before it works. It is EXATCLY one minute ten seconds from time of connect until it starts working passing traffic.
This is REALLY looking like a bug or incompatibility in the VPNConnect software with Windows 11.
I have seen several other posts about this but NONE of them have any kind of response or followup to them so I started THIS thread.
And I actually DO follow up on my posts whether fixed or not.
So far this is not fixed on my own and it’s looking possibly like bug report time if I don’t hear anything back.
I’ve only been troubleshooting this for about an hour so far.
I’ll see what kind of feedback this gets before concluding it’s actually a bug or compatibility issue.

Bump,
Not much help or interest here it looks like-
I’m going to go ahead and report this as a bug that is easily reproduceable.

No I did not. and not even an acknowledgement of any kind here.
My customer’s solution was to NOT use Windows 11.
It is many months later and I just tried this now on a fresh Windows 11 Install.
The problem is still present for me in Windows 11.
And since March 22 2022 There have not been any update released for OpenVPN connect. it is still the same version.
Did you find anything out?

Hello there,
I do see your posts here, but, at the same time, we have no other reports and Windows 11 tests okay on our end here. Now that doesn’t mean there is not a bug, but it’s also a problem, because in order to solve the problem, we need to be able to reproduce it here. So far it seems to just pass QA without seeing this issue.
Based on experiences in the past, it could be some particular configuration being used or a particular antivirus/firewall solution that can cause problems. Can you guys provide any information about what device is being used to connect to — are you both using PFsense’s OpenVPN server? And is there an antivirus/firewall program that both of you are using? Did you try uninstalling that, did you try connecting to another OpenVPN server? Because we need to find out what the common thing is that you two are experiencing, so we have something to investigate.
The only thing I see here that’s a bit out of the ordinary is the public IP being used for routing. Normally OpenVPN just uses the OpenVPN server’s internal VPN IP as the gateway address, and it then takes care of routing it to the right place. Maybe this is also something you could consider doing.
So, sorry, I don’t have an answer, but it seems a pretty isolated problem, and therefore hard to do anything with it. Maybe with more information we’ll get somewhere.
Kind regards,
Johan

Thanks for the reach back.
I will do some more testing.
In both cases the one at the beginning of the year and the one just now,
It’s after a fresh Windows 11 install and brought fully up to date (both instances) the more recent one is of course «more up to date» compared the test toward the beginning of the year using the same release version of OPenVPN Connect.
The VPN client works/passes traffic after waiting one full minute after it shows successfully connected
Always and consistently one full minute after connecting almost right on the mark.
There is no software or 3rd party firewall software involved on the computer running the client.
In fact I can turn off the built in Windows 11 firewall Or turn it back on /reboot and the problem still persists in exactly the same way.
I do not have any such problem testing under Windows 10 same computer same set of externals.
PFsense firewall is in place at both locations client and server.
Relatively simple configurations regarding firewall and openvpn settings, using pretty much out of the box configurations and VPN server setups.
Same problem with different remote openvpn PFSense servers.
It always works/ is suddenly able to pass traffic through the tunnel one full minute after connecting.
If you’d like me to provide further specific information or perform any specific tests /packet captures or detailed logging once it is turned on during the one minute of not able to pass any traffic through the tunnel that shows that it is up and working on the client versus once it start passing traffic I can.
I can also try different computers and different Internet connections/providers/hardware border firewalls as well on my end.
I am only seeing this behavior in Windows 11, clean install/updated with no 3rd party software yet installed (or after it is).
All things being exactly the same except with a clean windows 10 install — the problem does not occur.
Thanks!
Steve

I am seeing this 1m10s behaviour with Windows 11 and a pfsense OpenVPN server.
Could this be a pfsense thing?
I had another self installed and configured OpenVPN server with Windows 11 and I believe it came up immediately. This only started happening when I switched to pfSense.

Update: the delay is NOT 5-10 minutes before it works. It is EXACTLY one minute ten seconds from time of connect until it starts working passing traffic.

Hello,
Not sure. Possibly. It might be good to see the client log and see when for example the push_reply stuff comes in. The client will repeatedly request the server for instructions. If the server is uncharacteristically slow it may take some time before it gives instructions, after which the client will then implement those instructions. These instructions are usually about routing traffic through. But without logs I am just speculating. Maybe if the logs show that such a push_reply comes very late, then yeah, this may be a server-side issue.
Kind regards,
Johan

I have the same problem.
I will connect to the VPN and it will work then after some time it will stop sending traffic until I disconnect and then re-connect.
This started happening after a fresh re-install of Windows 11 22H2.

Hello pormiston, and others,
Can you give any information on what for example the routing table looks like when it is working correctly and when it has stopped working? There may be a clue in there. Something might be removing routes. To be honest we’re just guessing at this point. Our tests work but we see people reporting issues but we are not getting any logs or data that indicates where the problem might be. If the logs contain any sensitive data submit a ticket on https://openvpn.net/support instead.
Kind regards,
Johan

Greetings. I can also confirm the problem and wish to contribute my findings towards the solution.
I use openvpn connect client version 3.3.6 (2752). I am using a mikrotik router for openvpn server.
Initially i had no problems. The clients were getting IP from the 192.168.89.0/24 subnet. This was NATed through the servers IP. Everything was working OK.
I changed the clients’ subnet to 192.168.156.0/22. Then the problems started. Traffic was not passing through VPN. I tried with and without NATing this subnet, the result was the same. Occasionally, after adding static routes to client config, routing would work, but not always. After restarting PC problem would return. I must also note that currently the mikrotik openvpn server does not support route pushing.
When switching back to the previous /24 subnet, everything is working ok.
The problem does not seem to exist in android devices with the use of openvpn connect client and same config.
I installed openvpn community 2.5.9 . With the use of this client, everything is working normally. Strangely enough, after the above installation, openvpn connect client started routing the traffic properly as well. Maybe some driver got updated/downgraded?
I am not able to reproduce the problem from this PC now. However i might be able to reproduce it from another PC, so if i can be of any help somehow, let me know!

Hi
I face a similar issue to what Michiganbb experiences.
Using Open VPN connect 3.3.6 (2752) on Windows 11 Pro 22H2.
As Michiganbb described:
«The VPN client works/passes traffic after waiting one full minute after it shows successfully connected
Always and consistently one full minute after connecting almost right on the mark.»
In my configuration only a part of the traffic related to the corporate network is redirected through the VPN.
I checked what route was used to reach the <destination IP> using
tracert <destination IP>
Right after the VPN connection for one minute the non-VPN gateway is still used.
After one minute the VPN gateway is finally used.
I checked the routing table using ‘route print’ and the required VPN routes were active. But for some reason it took one minute for Windows to actually use them.
Regards

After running some more tests I can add the following observations:
The problem exists in windows 10 as well.
Does not seem to exist in other (non-windows) OS.
After modifying the clients’ subnet from 192.168.156.0/22 το 192.168.156.0/24, everything seems to work normally. Consequently, for my case I conclude that the /22 subnet mask somehow messes up the windows routes.
When checking the corresponding route in the windows routing table, the /22 subnet’s mask appeared to be 255.255.255.0 when it should be 255.255.252.0 .
I hope the above will help somehow. I may be able to provide more info and testing if needed.

Hi. I think I have the same or similar issue on Windows 10 Pro 22H2 19045.2486. OpenVpn connected to the server without any issue but look like it will not pass traffic via VPN.
I used remote VPN server which belongs to my friend. He gave me two key to use it from my Android mobile and from PC. From molibe all worked fine with OpenVPN Connect application. But it not worked from Windows PC with the same settings.
Last summer I installed OpenVPN Connect application fof Windows but this application not worked: it connected to server but not pass traffic via VPN. After several attempts to fix it with my friends I stopped trying and removed the application. But I found on site OpenVPN application here https://openvpn.net/community-downloads/ Surprisingly, but it started work and I used it till 13.01.2023. I dont know that happend but on that day Windows Update installed KB5022282 update. I don’t know if this is related or not.
Now it not worked, connected but not pass traffic via VPN. I reinstalled and updated OpenVPN to v2.5.8 (OpenVPN GUI v11.31.0.0) but there was no effect.

Whether you’re using a VPN for work, to stream videos, or to keep your online activity secure, Windows 11 VPN issues can be a real pain.
You might be dealing with the Windows 11 L2TP VPN not working, or perhaps SSTP, PPTP, WireGuard, or OpenVPN isn’t connecting properly.
No matter the exact error you’re getting, today we’ll help you tackle it. So, whether you rely on a corporate solution or a personal one, the steps below will help you troubleshoot it.
How can I fix Windows 11’s VPN if it’s not working?
Check out a quick video overview of the steps. For a deeper dive, be sure to read the full article.
1. Update Windows 11
- Open Settings from the Start menu.
- Click the Windows Update tab on the left of Settings.
- Select the Check for updates option.

- After that, click the Action menu. Select the Scan for hardware changes option there to reinstall the adapters.
- Click Power and Restart on the Start menu.
3. Flush the DNS
- Click the magnifying glass icon on the taskbar.
- To find the Command Prompt, enter the cmd keyword in the search box.
- Next, click the Command Prompt’s Run as administrator option.
- Input these separate commands by pressing Enter after each:
ipconfig /release
ipconfig /flushdns
ipconfig /renew
netsh int ip reset
netsh winsock reset
- Close the Command Prompt.
- Select Power, then Restart Start menu options.
4. Disable Internet Protocol Version 6
- Bring up the search utility with its handy Windows key + S keyboard shortcut.
- Enter network connections within the search text box, and click the View network connections app.

10. Reset Windows 11
NOTE
You’ll need to reinstall your VPN software and all other apps that didn’t come preinstalled with your desktop or laptop after resetting Windows 11. Therefore, resetting the platform is suggested as a last resort resolution.
- Launch Settings by pressing the Windows + I keys.
- Click the Recovery navigation option on the System tab.
- Press the Reset PC button for the Reset this PC tool.
- Select Keep my files within the Reset this PC window.
- Next, choose the Cloud download or Local reinstall option however you prefer.
- Select the Next option, and click Reset to confirm.
How do I enable VPN in Windows 11?
- Open the Settings app.
- Click on the Network & Internet tab on the left pane, then select VPN from the right.
- On the right pane, click the Add VPN button.
- Input your VPN parameters and click on Save.
- Now click the connect button, and you are done.
Why is my VPN not working on Windows 11?
- Third-party applications – Apps such as antivirus software are one of the main contributors to this issue. Unfortunately, a few third-party programs interfere with the VPN client, causing VPN connection problems. The VPN is, therefore, not functional on your Windows 11 computer.
- Drivers – A second factor contributing to the VPN not functioning issue on Windows 11 systems is problematic network device drivers.
- Windows Firewall – Windows Firewall blocks the VPN client. Sometimes, the Windows Firewall willfully blocks the VPN client network, causing your VPN connection to fail.
You’ve seen some potential causes of the VPN issue on a Windows 11 computer. In the following section, we’ll show you several tried-and-true fixes for the issue.
How can I manually add and connect to VPNs in Windows 11?
- First, press the Start button to select the pinned Settings app.
- Then select the Network and Internet tab on the left side of Settings.
- Finally, click the VPN navigation option.
- Press the Add VPN button.
- Fill out the VPN connection window with all the required details.
- Press the Save button.
- After that, you can select a Connect option for your VPN service under the Add VPN button.
Note that the solutions we will share are vital for many instances of this VPN problem, including Windows 11 IPsec, SSTP, Forticlient, PPTP, and L2TP VPN not working.
You will also find them helpful if your Touch VPN, Unifi VPN, or OpenVPN are not working on Windows 11.

Для подключения к своему серверу используй вот этот клиент.
Но придется погуглить как это настраивается. Давно подымал для общения ККМ с сервером.
На комп копируют ca.crt client.ovpn server.crt
Я тогда сделал самый простой вариант авторизации через auth-user-pass
Ставим опенвпн клиент
Закидываем в него конфиг
