About to lose advancement series because I'm locked out of the game?
I've played 4 games today. One to get into series, which went well. First game in series we had an afk and lost. Second game they had an afk and we won. Third game was a close match, but we lost. Fourth game, LoL decides to complain about being unable to connect to the server despite me restarting the client multiple times.
I guess, sorry to my team, I'll keep trying because it's about as fun as actually playing?
After ~10 minutes, I hit cancel instead of retry and then reconnected successfully? I dunno, hope it works for you next time.
