Hello,
A problem started after sometime. There was nothing changed on CI/CD pipeline.
I'm getting: There was a problem communicating with the license server

I know this problem is not really related to GameCI but could you give me a clue please?

[ErcinDedeoglu]

Incredible... Unity started forcing using TLS1.3, which was not supported by the host machine. apt-get update and upgrade solved the problem.

@ErcinDedeoglu How did you manage to do it inside a GitHub runner? I'm stuck with the same error
