OpenVPN Support Forum

Hi all.. I am REALLY tearing out my hair with this one. I am trying to establish a connection in a java program I am writing and keep getting the error
All TAP-Windows adapters on this system are currently in use. Also get this error when testing with the OpenVPN GUI

I have enabled it, disabled it, created new ones, uninstalled and re-installed, restarted... NOTHING works. Just keep getting this error endlessly.

TAP-Windows Adapter v9 is up when I check network connections.

I am running Windows 10. Any ideas please, I normally can solve these issues through a Google search, but this time every "solution" is to either disable and re-enable the adapter or uninstall and re-install, which I've tried both.. multiple times.

Here are the ovpn configuration file I am using, provided by NordVPN

EDIT: I removed the Java code... get the same error in the GUI


If you need more information from me please let me know! Thanks

This is not an installation issue.

Try using --dev-node in your config, see the manual for usage.
