This exact issue happened with me sadly. I was waiting for everybody to accept the que and then only 1 person seemed to not accept. It lagged for a good 15 seconds before the que dropped and I just thought it bugged out. Needless to say it did. I couldn't join any games due to already being in a game. I restarted and am now stuck in the reconnect screen.

Yup! same thing just happened to me too! Hopefully it'll be fixed soon.

Same thing happened to me. Tried to reconnect. Button turns gray. Nothing happens. I can login with a different account by my main account is completely locked on the reconnect screen.

Same thing happened to me, reconnect screen and all.

I just fixed mine right now by going to my internet browser go to tools deleat history and cheak all the boxs and clear everything if you use more then one browser say internet exploer and firefox do it for both then log in it should be fixed. hope it helped
