[solved]Inactivity Timeout every 120 seconds after upgrade to 2.6.5

Post by rubber_duck13 » Mon Jul 10, 2023 2:41 pm

After upgrading from OpenVPN 2.5.8 to 2.6.5, my VPN keeps disconnecting. Everything works fine if I downgrade back to 2.5.8. Installed on Truenas Core 13.0-U5.1 (in a jail). Is there any config changes that would have caused this? Using Torguard as my VPN provider.

Logs of issue:

Resolved, I ran the Torguard config generator for openvpn 2.6 (which I didn't realize existed). There was some additional items/changes when compared to my existing config, made some changes, everything is working again.
