I have linux and needed to access the vpn server without a client. I went to the config. generator and followed the instructions, but when i extracted the tar.gz file in the terminal the only files that showed up were the .opvn files. Nothing else, no user.key..nothing. So i followed the directions of configuring Airvpn with network manager and couldn't click apply once the .opvn file was imported. I selected servers by the country and didn't use a proxy when building config generation. I'd love to know what can be done to get this functioning with network manager, please. Any feedback would be appreciated, thanks.
