I’ve read that there are some server problems with the developer and that causes the error to come up way too often. Suggestion #1: The quick fix for when you get this error is to quit the game, then reload it.

With console gaming steadily growing, PC gamers have very little tolerance for buggy games. If the people behind it don’t put out some kind of update or patch soon, this game is going to tank big time.
