Cannot join or create a lobby with FAF Client v2023.11.1

[ZArS]

Getting a constant error when trying to join or create my own game (not modded).
Does anybody have an idea how to fix this?

Detatils of the error:
"Game could not be started. See below:

[ZArS]

Didn't see that advice, trying to check it.

@magge said in Uh Oh Game Could Not Be Joined:

Reason
Program is blocked or has wrong user rights
Make sure security software is not blocking the client
Make sure your windows account has rights to run the software
Remove "C:\ProgramData\FAForever" folder; and reinstall FAF
For testing purpose, run the client with admin rights.

[phong]

Firewall is configured to allow faf through.
VPN did not help.
Selecting Global coturn server did not help.

ice-adapter.log
client.log

[M9ICO]

the same problem, the removal and re-installation of the faf client did not give results.

[Volker4311]

ditto, uninstalled FAF & SCFA still getting errors. 2023.11.1 why you do this to us.

[ZArS]

@zars
Have checked all of that. Didn't help.
Can it be a problem with client v2023.11.1?

[MyHomieJoe]

mine is fixed now try reloading something may have not been working on their end

[MostLostNoob]

It was determined that there was an issue with the new managed Coturn server. That issue has been fixed & you should be able to play now.

[ZArS]

The problem is gone now after a regular reinstallation of the client.
Thank you all for the replies.

[Matr1]

I just started having these issues now, what fixed it in the end?
