rejoining games with steam issue.

Been having an issue where if a client leaves a game they can no longer find any sessions from steam. I have searched around and I cant seem to find any answer to this. And I mean any kind of disconnect. Now if I’m not connected to steam I can always find a session no matter how many times i disconnect. So I’m not sure if there is a special way to disconnect from steam when a player is disconnected or not. If any one has any info on this and can help me out, that would be great thanks.
