Likewise, I initially thought it was just the server still down for maintenance. I'm not so sure now as it would appear from other forum posts that the servers are back.

Interesting lots of other people are getting the exact same error as me. I've never had this before. The launcher updated as normal, but the game won't check, after I log in.

Can anyone say if they're back in yet?

Normally there's a maintenance follow-up, to say it's finished.

If this persists, I'm going to be a very pissed of customer now. What with all the issues. This, sadly, will be the straw that broke the camels back.
