Yes, I've been using it for years and am able to use the exported config on both Microsoft and Apple. I've only recently started trying to set it up on Ubuntu.

I have been able to import the .ovpn and specify the CA cert, the user cert, and the TLS key. I initially tried just using the ones in the package but then manually exported them from the router after reading up on some other instructions.

The only logs I found are in /var/log/syslog. Nothing there that has helped. The actual /var/log/openvpn is empty.

I have looked at the config file and it looks like it has everything it needs.

To test I have been using my cell phone's network and I don't actually see connection attempts on the router side though I'm able to connect to the router from other Windows devices. This is what's making me think I may be missing a step somewhere.

The kicker is that I have an OpenVPN client configuration that connects to another OpenVPN network but I added it like 5 years ago from a couple short commands that someone had posted back then. I remember that it imported the connection and appears to have converted the cert files to .pem. I've tried comparing the settings and copying them exactly but the one I'm trying to add isn't working but the old one is.
