Jellyfin wont load to UI

[kira100000]

Issue:
Jellyfin has been running perfectly on my server until today. I haven't made any changes that I’m aware of, yet now it won’t load past the splash screen.
Symptoms:

• Accessing Jellyfin via
  http://servername:8096
  or
  http://ipaddress:8096
  connects but gets stuck on the splash screen.
  
• Screenshot: https://imgur.com/a/6500dE5
  
• The server is reachable via ping.
  
• The issue persists across multiple attempts:
  • Restarting the Jellyfin container and the entire server.
    
  • Clearing browser and site cache.
    
  • Testing in incognito mode, a different browser, and the desktop client.
    
  • TV apps also fail to connect.
    

Additional Context:

• Tailscale is installed on the server (not sure if relevant).
  
• Installation method: Used the YAMS installer.
  

Logs:
Here are my most recent Jellyfin logs: http://pastebin.com/9QBQT52e
Any help would be greatly appreciated! Thanks in advance.

The fact that Jellyfin only sees the Docker bridge IP tells me that it isn't port publishing. Is another app handling connections? Like Nginx or something?

It's not using any reverse proxy. It is using tailscale as far as remote connections go but this is happening when accessing on my home network.

I'm not familiar with YAMS, but it looks like something changed with how the docker container was setup. As is, the container is not accessible except from the host running Jellyfin. You have to configure the container to run in host networking mode or publish port 8096.

Docker container is showing published to port 8096

Its strange that it does seem able to connect (not returning any connection failed)
For instance on the desktop client and I can input the IP and port and it will look like it loads the jellyfin logo but will not actually go into the UI

Does this happen only with the desktop client or with all clients?

It seems like Jellyfin is having trouble loading past the splash screen, even though everything was working fine before. Since you've already restarted the container and the server, cleared caches, and tested across multiple devices, it's likely something in the backend, like a database issue or a plugin conflict.

I’d suggest checking the logs for any specific errors—there might be something related to the database or a plugin causing the hang. You could also try renaming or moving the config and data folders to let Jellyfin start fresh.

Happens on loading the web version and desktop client. If connecting from a tv app it throws a connection failed.

Will try removing config and letting Jellyfin restart and rescan everything if I can get in. Was trying to avoid having to do that.

[TheDreadPirate]

Instead of deleting /config, you could make a backup so you could restore if it a fresh Jellyfin setup doesn't resolve the issue (I don't see why it would).

Through googling I saw a solution that seemed to be the same issue where someone simply switched their network to private instead of public. Not sure if this would do anything as its been on public and was working before.
