New Jellyfin Server/Web release: 10.11.3

[GreenDruid]

Just had an issue after updating to 10.11.3 on Windows 11.  I was unable to access any libraries stored on my external drives but could still access libraries on an internal one. When trying to play a film the player tries to load the media but the spinning circle would just spin and nothing happens. I did access the logs and this was the error:

[2025-11-18 01:27:29.976 +00:00] [ERR] [24] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request: "Incorrect function. : 'F:\Media\Movies\The Adjustment Bureau (2011)\The Adjustment Bureau (2011).mkv'". URL "GET" "/Users/bb8fc2a820eb41e5ab50a643e4b56351/Items/ba12fa4f1f25dcd0d45ace4224d9b803".

I uninstalled and reinstalled 10.11.3 a total of 3 times but unfortunately this didn’t solve the issue. In the end I uninstalled 10.11.3, deleted my Jellyfin data folder, then reinstalled 10.11.2. Everything seems to be working again.

To try and recreate it I did upgrade again to 10.11.3 leaving the Jellyfin data folder intact and once again all media in libraries on external drives is unplayable. Downgrading to 10.11.2 allowed all media tp be played.

Cheers for all the hard work.

Can you please make a bug report on GitHub: https://github.com/jellyfin/jellyfin/iss...report.yml

Please provide as much info about the storage media(what type, filesystem, how it's connected, etc.)

ok - i have massive problems since 10.11.0

android tv app always crashing and everything sluggish.
11.3 seems to have finally fixed the app, as i was able to show movie/show lists without the app instantly freezing and crashing.

still sluggish and lots of errors in the log.
scan all freezing at 57% or not starting at all and hanging at 0%

so I started with a fresh 11.3 install

let it scan in all movies/shows no problems. blazing fast again and seemingly no grave errors in the log.

added my music library - initial scan took forever but ran through without errors.

when I now start "search for missing metadata" on the music library jellyfin crashes and reboots 
edit:
did some digging
- crash log has

Code:

in
[*]MediaBrowser.Controller.Entities.Folder.ValidateChildrenInternal

and

Code:

MusicArtist.ValidateChildrenInternal
.
[*]LimitedConcurrencyLibraryScheduler.Enqueue"

[*]
and

Code:

"System.ObjectDisposedException: Cannot access a disposed object.

Object name: 'IServiceProvider'."

- deactivating musicbrainz did nothing
- setting "parallel library scans" to "1" seems to fix it (at least I'm currently at 54% scanned and no crash after the first single digit % scanned)
- I'm also getting lot's of Auth errors:

Code:

"[font=monospace][color=#000000][10:07:50] [INF] [32] Jellyfin.Api.Auth.CustomAuthenticationHandler: CustomAuthentication was not authenticated. Failure me[/color]

[*]Sounds like symptoms of database locking.

[*]MASSIVE database problems since 10.11.0.

No noticeable differences for me, though from the changelog there were some bugs I wasn't aware of that were fixed. I still have slow library loading, slow loading on Music (Roku takes forever), Home/Video is broken when using nested folders, Books has the same issue.

"other" library (for me tvshow/movie other for youtube) it still spins forever with nothing showing in the log file. Works fine in 10.10.7, i dont have logs that are least bit helpful for this, it shows zero info for that.

Had the exact same issue on win 11, good to see I'm not the only one. I did not even realize that it was my external media that was unplayable. But since all of it is external, nothing worked for me. Had to go back down to 10.11.2 which works fine.

Did you open an issue for this already? I would do it myself but I did not save any of the logs.

Cheers!

Hey everyone, first off huge thanks to the devs and everyone contributing, Jellyfin is awesome and keeps getting better!
Just wanted to mention the only remaining issues I’m seeing after upgrading to the latest version:

Some shows with virtual seasons no longer create the virtual season during a regular library scan. This mostly just applies to anime using shokofin as it doesn't use the standard "season 1" type folder structure that TV shows use. I have to do a full “Refresh metadata (replace all)” on the series manually. Spent a few days fixing all the affected shows – time-consuming, but at least it works. I'm unsure why some created virtual seasons fine the first time and why some just added the series with blank seasons.
With thousands of collections, enabling “Group by collections” slows the library down massively. Even after dropping items per page to 20, pages still take 10–20 seconds to load (it loads eventually, but wow). This wasn’t an issue before 10.11.x for me.
Adding items to collections via the UI just spins forever (probably because of the huge collection list). I’ve been editing the collection.xml files manually as a workaround.

None of these break core functionality, and I have workarounds, so I’m really not complaining just reporting in case it helps. Thank you again for all the hard work!

Thanks to all who work and contribute to this, Jellyfin is a fantastic resource! I have a small issue that's started with the 10.11.1 release: my SDR videos ripped from DVDs are all transcoding on my webOS LGCX TV. They used to direct play fine, but now they transcode with a message saying that anamorphic video is not supported. 1080p HD and HDR content direct plays fine, just the 720p SDR content. Any insight on why this is happening would be much appreciated, thank you!
