Hi all,

Trying to connect to the below nordvpn server using the server config file alongside providing username and password options. However every iteration tried is failing. I previously tried wireguard however it just silently fails.

The error appears to come down to this in the logs, however googlefu is failing to help me move forward or even identify where to go.

2024-08-27T13:57:57Z INFO [openvpn] Error: problem with tun vs. tap setting
2024-08-27T13:57:57Z INFO [openvpn] Exiting due to fatal error

The closest links I can find refering to the issue just go to the solution of adding UPDATER_PERIOD which doesnt seem amazingly related to the error message, ive ofcourse tried it though without success.

Im using Gluetun on kubernetes with the below config:
