I think the error message is straightforward:
Message: LeaveRoom failed: user is not joined in any room.

That's it. A client sent a LeaveRoom request but he was not joined in any Room. This doesn't really cause any harm but it indicates that you're probably not handling all the game states.

For instance, if a client fails to join a Room he shouldn't be allowed to send the LeaveRoom request, since there's no room to leave.

In any case, as I said, this is a warning that causes no real issues.
