Connection issues / No authentication:

[LV|Ironstorm767]

EDIT: Seems I got ahead of myself, as the authentication fix was only server side and therefore no actual update was released.

A more permanent fix will be worked out on Monday or Tuesday.

If you're still having issues, and on Windows, see below.

If you're on Linux or Mac, and are having issues. Please comment below.

Edit: With the fix only being game server sided and no actual update. You can try the "ExceptionOnConnect" error suggestions:

I had this problem too. Now it works perfectly for me. I solved the problem with this instruction.

1.Click the Windows Start button.
2. Type Cmd in the Start Search text box and press Ctrl-Shift-Enter (keyboard shortcut to run Command Prompt as Administrator). Click Continue to allow elevation request.
3. Type netsh winsock reset in the Command Prompt shell, and then press the Enter key.
4. Type netsh int ipv4 reset in the Command Prompt shell, and then press the Enter key.
5. If you use ipv6, type netsh int ipv6 reset in the Command Prompt shell, and then press the Enter key.

Note: you may need to run Network Diagnostics afterwards to "repair" your connection after this. *added from the Support Guide*

I'd test them individually, and not all at once.
