Diablo III’s error code issues/log in issues aren’t the only thing you should be worrying about dear readers. Other mysterious errors may occur, like a certain game breaking bug which was discovered by other players who were actually able to log in. According to the Blizzard forums, some players have found that if you give your Templar Follower a different shield or anything else for that matter…the game will de-synchronize from Blizzard’s servers. This results in the 3006 error code when you try to log in, even if you’ve restarted the game. Blizzard has offered a solution to this which includes flushing your DNS and restarting your router but players have tried this and say that it does not work.
Other issues include the log in problem which we have detailed here.
Hopefully Blizzard works out the kinks for Diablo III soon.
