Error Jellyfin Docker container is "unhealthy,"

[Yaichi_JK]

The logs indicate that the Jellyfin server encountered an unhandled exception related to WebSocket connections, specifically an
ArgumentOutOfRangeException
. This exception suggests that the server attempted to access an index in a collection that does not exist, which led to the crash.
