I can't connect with Creative Cloud on my Mac

Hello there! 

I just installed the Creative Cloud application on my PC and Mac. I had no problems logging into the Cloud on my PC and I was able to download programs like PS ect. Then I tried to log in with the same account into the Creative Cloud on my Mac and I get a Message saying that there was an Error and that I should try logging in later. I already checked and tried out some stuff. First I restarted my Mac, then I reinstalled the Creative Cloud. Then I logged out of the Cloud on my PC. I also made sure that I had only activated my Adobe Cloud on less than two systems which of course I had because I just bought the cloud and just activated it on my PC. I just updated my Mac to Big Sur as well to make sure that there wouldn't be any compartability problems. 

Right now I just don't know what else I could do. If somebody could give me some advice I'd be very thankful. 

Much love
