Media Player not working after server update

[Mussaka]

Ok, It worked for me.

Thank you

In a browser, go to your Jellyfin and then Dashboard > Devices.  Delete the session for Jellyfin Media Player.

On the system with JMP, go to C:\Users\yourUser\appdata\local.  There will be a folder called "jellyfinmediaplayer" and "Jellyfin Media Player".  Delete both.

Open JMP and log back in.

Do you know how one would do this on a Firestick? I tried deleting cache and data, before and after reinstalling, bur I can't locate the JMP folder to completely remove.

This is only for the Windows/Mac/Linux desktop app.

What issue are you having?

This seems to also happen on Android...

Under Android: go to your Preferences--> Apps-> Jellyfin -> delete data -> delete cache

The client can browse my library fine, but the internal player stalls immediately on a black screen when I try to play them. Seems to be universal to all file types and encodings.

Thanks. I did try this first, but it didn't seem to help. I'll give it another go tonight.

For anyone still running into this: I just had the exact issue as OP after upgrading to 10.9.11 running a Flatpak instance. Deleting the Device from the admin dashboard and also deleting 'jellyfinmediaplayer' and 'Jellyfin Media Player' folders was not effective. Deleting the entire Flatpack folder (~/.var/app/com.github.iwalton3.jellyfin-media-player/) and reinstalling solved the problem.

Thank you so much for this post!
I also had this issue after upgrading to 10.9.11 on my server
(Server version 10.9.11
Web version 10.9.11
Build version 10.9.11)
while running a Flatpak instance on my client (JMP 1.11.1 on an old laptop running Linux).
I also found that the previous solutions did not work, but your solution did work. I had to implement your solution with JMP installed, or else the main directory would disappear on me.

With JMP closed, I ran this:

sudo rm -r ~/.var/app/com.github.iwalton3.jellyfin-media-player


Then I ran this but it replied that JMP was already installed:

flatpak install flathub com.github.iwalton3.jellyfin-media-player


After that I launched JMP, entered the server address and login, and everything was fully functional again.

I ran into the exact same issue described by the original poster (I'm running the JMP on Windows 11), but unfortunately, nothing I read here helped.

What fixed it for me was to run the Jellyfin Media Player "as administrator" (right-click on the exe and pick "Run as administrator").
Hope this helps someone!
