I feel you on that. The first time I set it up, it me forever. I finally figured out the issue was it was not picking up the right IP address for my server. Once I fixed that, and knew to look for that in the future, no issues. I tore my whole server down last weekend, and transferred all the drives to a different setup, rebuilt the server and have everything working, logged back in on all my devices in an hour tops. Everyones milage will very though

Oh 🤷‍♂️ I guess I never have issues with that.

How so? I have way less issues with jellyfin than I did with Plex. I think with jellyfin you just need to RTFM and find some plugins to expand the functionality if you need it
