My main issue is that I cannot play with matchmaker as it fails to connect me despite my internet connection and speed being ideal and never fluctuating. I want to play but feel bad now because I am causing these games to fail. And on the occasions I do get into a game, the connection in game is perfectly normal. the issue seemed to start with 3v3 games, and I could play other modes just fine, but now its disconnecting from all matchmaker modes. The connectivity indicator in the bottom right corner never says that I am disconnected. Regardless of who else is online near me, the connection always fails. I have no problem joining custom lobbies and I can run replays without a hitch.
update: cannot seem to connect to lobbies. tested my bf's account who is right next to me and he was able to connect without a hitch to a 1v1 matchmaker.
