I never experienced issues like this before but this season (in which I played only the last couple weeks or so) it became more and more frequent, seemingly in all 3 regions. Before posting this bug report, I could barely create games on the EU servers.
I press play and wait for 30-60 seconds on a “Creating Game…” screen that can’t even be cancelled only to find out that game creation has failed. If the game doesn’t go to the loading screen within 1-2 seconds it seems to be quicker to just exit the game (with the X button of the window) and restart it because it’s faster than waiting out that unreasonably long timeout.
