No. I've spent hours googling my problem and trying every solution that popped up. The server is behind a router, and no amount of port forwarding and firewall permissions is getting past it for whatever reason.
Are you on apartment internet by chance? You've probably got a double NAT. In which case you'll need a server, outside the network, that can make a tunnel to your server.
There are a few things plugged in to that router that I've never had an issue accessing, but they just need basic Internet access as far as I understand
I had a similar issue in my home where I ran a nighthawk router at the back of my house connected to the ATT router/modem at the front of the house. I let them run as separate networks for a long time, and that prevented anything not connected to the same router as the jellyfin server from seeing it.
I recently got my act together and switched the router to "access point mode" and the house is all 1 network now. The jellyfin server is available on everything in the house as well. After the change, I felt silly I had it the other way for years because it sure helps many of the other wifi objects in my home as well.
Yeah I've been running Jellyfin for a year now and it's amazing. The plugins automatically find metadata, cover art, and subtitles for me as soon as I upload them to my nas.
