I’m playing on a private servers with a couple of friends and all of us randomly get the same error when trying to log in:
“Authentication failed”
Sometimes it’ll let you log in after a couple of tries but most of the time it just won’t let you join the server at all (even if you try 10 times or more!). Restarting Steam or the PC doesn’t help and usually that person simply can’t play that day.
A server restart helped a couple of times but there’s no guaranty that it always will and honestly, having to restart the server just so a player is able to join just sucks!
How can we fix this?
Edit:
It got so bad that eventually nobody was able to join anymore unless the server was restarted, and even then it often took multiple tries to get in.
The server admin contacted the host (nitrado), they changed something (according to some info by Funcom) and nobody’s had the problem since.
