I am running Jellyfin 10.10.6 in a docker container, on Debian12 on RaspberryPi 5
I have a self hosted gethomepage in another docker container that has Jellyfin as one of the services, and uses a native plugin to connect to my local Jellyfin server; it retrieves the necessary information, and presents them in the homepage (for example number of hosted movies, episodes, songs, and in case some user is viewing a movie details on what is being played)
Up until a couple of days ago it was working properly, but after an OS update/upgrade and reboot, it is showing an API error instead of the Jellyfin information
I attempted to connect via browser to other Jellyfin API URLs with different API keys and they all work properly, but all iterations of http://mylocal.domain:8096/emby/Sessions?api_key=*** fail with an Error processing request
The Jellyfin logs around the timestamp of my attempts from browser are perfect matches to the many more instances of the same errors in the logs (supposedly the gethomepage Jellyfin Plugin attempts):
I seem to be unable to identify from the log the root cause of the issue, where could/should I look next?
Thanks in advance for any help
