After taking a break for a brief lunch (I know, bad idea) I’m trying to log back in and the games cycling between Error 37 and Error 75 now. I haven’t been able to find a cure for either error other than just trying again. Error 37 means that the servers are busy, but I’m not sure exactly what Error 75 means. I’ll update this post as I get more details – but the best advice I can give you is to keep trying. Once you get past the combo of Error 37 and Error 75 you’ll sit at the hero select for awhile. As of the writing of this post they’re performing emergency maintenance on the North American servers that will hopefully fix the connection issues.
Update: Error 75 describes a temporary outage of the Battle.net servers. Basically – no solution just try again.
