The room no longer exists. The session ends exactly as if the host had closed it.
Retries ran out (about two minutes). The session is still mounted but signaling is dead: the user should leave and rejoin.
The consumer left the room deliberately while recovery was running. Not a fault.
The server evicted this connection for a newer one with the same identity (another tab or device). The session ends.
The server ended this connection on purpose. The session ends.
Why a recovery ended without reconnecting.
