This happened to me many times so I got to report this. I keep getting banned of games not because I left games or lobby but only because the game failed to start. Your server or something is so buggy that it prevent me to connect to a new game and the system thinks that I left the game. So it results in a temporary ban of 5 minutes. PLEASE FIX THIS. I am tired of having to wait while I did nothing wrong.
Thank you for reporting @NameW6209! I feel your frustration here.
When your game fails to start, are you seeing a specific error?
