This has happened to me many times this season and it resulted in me getting banned from comp this season. It finds a game then says at the top “connecting to server” then keeps doing that until it kicks me from the game and I get handed a ban. I can even see the game’s text chat while in the main menu while unable to join.
What I think causes this issue is sometimes I finish a comp game and then super quickly go in queue and wtart searching again for a game. Not sure if this is what causes it but I suspect it.
