OpenVPN template and server settings

I’ve been struggling for the past week trying to get an RV50X to connect to an OpenVPN in a docker instance - with no success. I believe I’ve tried everything and debugging isn’t showing anything useful. Connection with other OpenVPN clients is no issue.

Can someone share an OpenVPN config setup and ALEOS template that is known to work? I just need a starting point from something that actually connects so I can customise from there. Using the latest ALEOS 4.11 and OpenVPN server 2.4 .
