So, it's been a month since I got this error. I still can't play. Support doesn't help. I did all they told, all solutions I could find myself. Nothing helps. Because it's a server side problem. That's it. It's total bs that it's something with my provider. I have tons of online games and i have zero problems. It's just server issue. It's a dev issue. And they totally fail to fix it. Very poor start for a paid alpha access. Totally disappointed.
