Been trying after every update. Had some success with this most recent one. I tested in multiple lobby sizes and tracked my success at loading in over ten games and kept track of what servers were hosting the matches.
First game 8v8, loaded fine on North Central US server, played game, won.
Second game 8v8, couldn't load in, east US server, got the connection interrupted error.
Third game 8v8, west US server, loaded fine.
Fourth game, H3 Team Hardcore, East US server, couldn't load in.
Fifth game, H3 Team Hardcore, South Central US server, couldn't load in.
I then reset my router yet again and tried a 6th game. H3 team hardcore, north central US server,, loaded fine though there was slight lag in game.
7th game, H3 Team Hardcore, West US server, loaded fine.
8th game, H3 Team Hardcore, west US server, failed to load in
9th game, MS 2v2, North Central US server, failed to load in.
10th game, H3 Team Arena, South Central US server, failed to load.
Bearing in mind that when I bought this game originally, I paid $60 for it and never had a problem until January 2019, this is really -Yoinking!- pissing me off 343!!!
