How can I fix OpenVPN not working on Windows 10?
1. Add an exception to the firewall
- Press the Win key, type firewall, and open Firewall & network protection
- Click Allow an app through the firewall
- Click Change settings (you need admin rights)
- Search for OpenVPN in this list and check its boxes for Private and Public
- If it’s not in this list, click Allow another app to browse and select it
It’s possible that your firewall didn’t whitelist OpenVPN when you installed the client. In that case, you have to manually add an exception for it in the system firewall.
If another application is responsible for your computer’s firewall, make sure to adjust the above settings accordingly.
To quickly test this theory, you can temporarily disable the firewall and check if OpenVPN works properly on Windows 10 now.
But don’t forget to turn it back on since you risk exposing your home network to vulnerabilities.
2. Use a reliable VPN client with OpenVPN support
If you’re trying and failing to get the OpenVPN to work on Windows 10, consider getting a commercial VPN app that supports the OpenVPN protocol.

3. Whitelist OpenVPN in your antivirus
If your anti-malware application throws errors when you try to use OpenVPN on Windows 10, it could mean that it’s blocking the client or protocol.
However, it’s a false positive. In that case, make sure to add OpenVPN to the whitelist to prevent your antivirus from blocking your VPN.
As in the previous solution, you can quickly test it by temporarily deactivating the real-time detection engine of your anti-malware tool.
But we suggest turning it back on as soon as you finish the test and not leave your computer exposed to malware attacks.

4. Reset the TAP adapter
- Right-click the Start button and select Device Manager
- Expand the Network adapters menu
- Look for any TAP drivers, right-click and select Uninstall device
- Open the Action menu and select Scan for hardware changes
The OpenVPN client requires a TAP driver to work properly. If its functionality is broken, it could be the reason why OpenVPN is not working on your Windows 10 PC.
However, you can easily fix this by uninstalling the TAP driver from Device Manager – it should get automatically reinstalled.
As a general rule, it’s essential to keep Windows drivers updated to the latest version.
5. Check if the DHCP service is running
- Press the Win key, type services, and open Services
- Right-click DHCP Client and select Properties
- Set Startup type to Automatic
- Click OK
Many OpenVPN users report seeing the Initialization Sequence Completed with errors message on Windows 10.
It signals a problem with the DHCP client, which you can restart using the instructions above.
6. Flush DNS and reset Winsock
- Run Command Prompt as admin: press Ctrl + R, type cmd, hold Ctrl + Shift, and press Enter
- Copy and paste the next lines (press Enter between each line)
ipconfig /flushdns ipconfig /registerdns ipconfig /release ipconfig /renew NETSH winsock reset catalog NETSH int ipv4 reset reset.log NETSH int ipv6 reset reset.log exit
Restart your PC to apply the new changes.
The DNS cache and Winsock configuration are responsible for your computer connectivity.
If they’re not initialized properly, it could be the reason why OpenVPN isn’t working on Windows 10.
To recap, if your OpenVPN configuration fails to work on Windows 10, you can fix this issue by adding an exception to the firewall and whitelisting OpenVPN in your antivirus.
You can also reset the TAP adapter, check if the DHCP service is running, as well as flush your DNS and reset Winsock.
