Web interface gets stuck on loading screen

[sang-ook]

Describe The Bug

When I deploy the latest version of Jellyfin via Portainer on Raspberry Pi 4, it gets stuck on loading screen. There were a similar bugs mentioned in #2493 and #2494. Well, I do have plugin section in my config.json file and the same issue is still happening.

Steps To Reproduce

1. Deploy the latest version of Jellyfin via Portainer.
2. Go to Jellyfin's web interface.
3. Get stuck on loading screen.

Expected Behavior

Web interface should show initial setup page.

Look for errors on Network and Console tabs (Developer Tools). It might be an issue with stored credentials.

[pto199]

This has been a problem with 10.7.x . Try to log out and log back on. That usually clears the issue. Nobody is working on this issue unfortunately it seems because its seen as an upgrade issue, but it is in fact an occasional problem on fresh installs too.

[sang-ook]

Deleting cache and cookies solved the problem.

[wkearney99]

Cache and cookies didn't solve it here. Used an entirely different browser that'd never been logged into the server and still getting periodic messages: [2022-06-13 17:06:00.104 -04:00] [INF] "CustomAuthentication" was not authenticated. Failure message: "Invalid token."

I'm getting it with a fresh login, playing some mp3 tracks, and going to the next track burps this specific set of errors:

If you are using a reverse proxy, then disable caching to fix (fixed it for me)

[DavidMikeSimon]

I was also experiencing this issue when reverse proxying through nginx. Disabling caching on nginx (both client-side caching and proxy caching) didn't help. The only workaround was to hard reload the client, on every site visit.

Upgrading to the latest version of Jellyfin also appeared not to help. However, after also deleting all local storage for the site on my browser (e.g. in Chrome devtools, Application->Storage->"Clear site data"), everything then started working correctly!
