No.

FYI usually that message "possibly because you have logged in somewhere else." is wrong, rather it is some other communications problem. You might try connecting to a VPN before starting the game if you have one.

The Nightwave said: I usually play this on multiplayer and is a big issue for me, obviously… perhaps they are having trouble with their servers? Don’t know… I’ve sent a ticket. I hope they respond.
This game has a choice of Steam or Nakama MP servers, do you get this whichever one you choose?
