I've been having this same issue for months now. When I first started playing the game back in July and I had no issues. Reinstalled windows due to issue with my PC and have been having these problems since. I've tried everything everyone else has said and I'm lost as this point. The problem was manageable before but since the spike in queue times it's an absolute killer. From what I've seen there's quite a few other threads like this one and there has not been an official response from SE. I would also not expect one either considering this issue seems to have been going on for a long time and has yet to be addressed.
