StarStable does not connect to the server?

When I wanted to log in to SSO a few days ago, that actually worked, but only when it was supposed to initialize, came shortly after the message "Your computer can't connect to the server Check your Internet connection or contact the customer support" I I have already uninstalled SSO and downloaded new and restarted the laptop several times but it does not work. What can this be? And what can I do there?

Do exactly what was there, so write down the support. They already give you instructions.

Well, German support is always understaffed and takes a long time to respond. Do you know what else you could do?

I always answered the support within 2 days. At most, the 3 needed. Otherwise you could restart your router times, but no idea if that brings something.
