Reviewing my server logs when clicking the cast button reveals (did 10.10.0 change the Sessions structure?):

It seems to me that this commit in 10.10.0 made a change to how the User object is loaded to handle API keys:

jellyfin/jellyfin@5ead283

and perhaps the Android app is not sending the user's Guid to the Session API endpoint?

Sadly i am experiencing the same issue using the official android app, trying to click the "Cast" button results in a never ending "loading spin".

Hopefully this gets looked at and fixed fast, considering a downgrade to 10.9 so i am able to use my server again.

[DarkNeroXIII]

Thanks! I do have the exact same issue right now. At first i suspected a newly installed Plugin but trying around made clear it was just the upgrade to 10.10. (I do run Jellyfin directly in an lxc container without docker)

So far i did not find any solution sorry, i am trying some things

[Maxr1998]

Definitely possible that the Android app isn't sending compatible data currently, but this also seems like a server issue since it really shouldn't log this kind of exception. I'll have to look at the logs of the Android app if those contain more actionable info for us.

EDIT: I just upgraded to 10.10 and checked it myself and unfortunately couldn't reproduce the issue (on the release version, so 2.6.2). Not sure what's causing it.

See jellyfin/jellyfin#12717 You should be able to reproduce it with an non-admin user.

This issue is already fixed for 10.10.1, closing as duplicate of jellyfin/jellyfin#12717.
