I can’t remember what I did, but I had it so the user just had to know the ip address and the port. Enter that into the jellyfin app on a tv and they could hook up pretty easily. That was with a reverse proxy I believe but I’m not really great with the setup, just followed a tutorial.

I’ve accidentally turned on speed limits in Qbit before

There’s also a client called Jellyfin Media Player that works pretty well. I tried Kodi one time and really couldn’t stand it. Felt so cluttered and clunky to me.
