[Client] [Serverproblem] Assigned to an already ended game

Hey guys. I'm experiencing a rather annoying bug. I'm not able to play due to a bug where i'm somehow assigned to an existing game and because of that can't start a new game. I played a ranked game and 2 minutes in the enemy team decided for a redo, due to a player who didn't connect. The game ended and i'm back to the main page. I get the message that i have to relog due a server problem where im assigned to a game. I then relog and now have the opportunity to reconnect. I have tried that, but it loads up a black screen, and after a minute ot two i get the message that i can't connect to the server

-Please help.

Have you had the same bug, and how did you fix it ? :)
