Hello again,
Althought we have this [Auth] SSO error for some time, I never came across to a final fix.
- Have you tried to repair the client?
- Try launching the game from the Steam Folder instead.
- Usually the game fixes itself in the moment you re-install the game.
Also, are you perhaps using a VPN?
