If you’d like to stick with transmission, this docker works very well: haugene/transmission-openvpn

I’m running their docker and it works pretty well. Never have to touch it except for updates.

I’ve been running OC10 for a while now and have hit a few bumps here and there. I didn’t realize OCIS is available as a self hosted thing. Since first reading this thread a while ago I’ve been working on getting it running. Using docker I manage to get it to open to a blank blue page where I’m supposed to be able to log in but the form doesn’t show up no matter what browser I use. I may look into it again in the future…
