Xcode cloud setup not working

I finally signed up for Xcode cloud, but it doesn't work after successful GitHub app installation.

401 in the console for: https://appstoreconnect.apple.com/olympus/v1/providerSwitchRequests

I tried multiple things, even wrote to apple.

Is it only for payed GitHub users? I have a free private repo.

Hope someone has an idea.

This is the error message when I give Xcode Cloud access to all repositories:

Die Verbindung von Xcode Cloud mit deinem Quellcodeverwaltungsanbieter konnte nicht erstellt werden.

Translation: The connection from Xcode Cloud to your source code management provider could not be established.
