Loading Webpage "hangs" until reload with CTRL + SHIFT + R (without cache)

[DaRealHansForSure]

Describe The Bug
Every now and then, when you call up the Web UI, it gets stuck at the Jellyfin logo.

In the Network tab you can see that it is no longer loaded as the main chunk.
However, if you call up the page again with CTRL + SHIFT + R, everything loads normally.

This happens from time to time. Disable Cache in the Network Developer does not help either.

Version 10.8.z rlease of jellyfin-web works as expected.

Steps To Reproduce

1. Start instance with web 10.9.1
2. Finish the first setup
3. Login
4. Wait some time, and call the jellyfin web page again

Expected Behavior
Loading fully Web UI

Logs
No Errorlogs appears in Browser.

I have just made some additional observations.

When this error occurs, I see activity on the “” element in the DOM in the Dev Tools, but nothing is effectively changed visually (too fast)

Also experiencing this issue on Firefox 125.0.3 for Linux Mint, using the same version. It only began occurring when I upgraded.

That's the old logo.
Do you use a reverse proxy (you on Windows, but still)?
Some proxies can cache a lot.

[ItzzCode]

Not the OP, but it occured to me even though I connected directly to the Jellyfin Server without a reverse proxy (inadvisable I know, but eh).

[DaRealHansForSure]

Sometimes it runs behind a reverse Proxy, but Caching is disabled, and also after a fresh reload it don't work.

Same occours sometimes lokal without Proxy

I have experienced the same issue. Had to downgrade to 10.8 due to it.

I experienced this bug already in a early state of 10.9 Web as Information

I've also been experiencing this issue.

Server running on Debian 12, accessing from Firefox and Chrome on both Windows and EndeavourOS. When it happens again I'll need to test accessing it without the NGINX reverse proxy, however restarting the service on the server seems to fix the issue temporarily.

also experiencing this issue since 10.9.1
browser: brave, firefox

jellyfin is hosted on docker within a synology nas behind the synology.me proxy

solution was for me to force renew cache CTRL + SHIFT + R

Also experiencing this

Hosted on Docker.
Hangs on everything I try it on. Edge, Chrome, Floorp, and Android.

Can only access it with Jellyfin-vue frontend or Jellyfin Media Player.

Found no solution so far. Even clearing cache and cookies didn't help.

Nevermind, this was due to some jellyfin modifications I did to main.*.bundle.js and completely forgot about. Deleting those mounts and repulling the docker image fixed it for me without clearing any data.
