The Rhino Accounts server could not be reached

Hi,
I have been using Rhino 6 for many years on my Windows 10 computer. I just received my new Windows 11 computer and installed Rhino 6.3 on it which seemed to work fine. When I try to start it, I’m asked to login which also seem to work, but just when I have done that I get the following error message:
“The Rhino Accounts server could not be reached. Please make sure you are connected to the internet.”
I have closed Smart App control in Windows. I added a TCP 443 port allowance in Norton 360. In Norton 360 under program controll there are two Rhino 6 listed one with the Rhino logo and one more basic list logo. Both are green allowing in/out.I have also tried to turn of the Norton 360 and Windows Defender Firewall.
But I always get this “The Rhino Accounts server could not be reached.” error message and can’t open Rhino.

Any suggestions? (I’m not good all these things so I might missed soemthing).

Best regards,
Magnus

Can you reach these sites via a web browser?

Thanks,yes I can reach all three.
But still get the same error message after login when I try to start Rhino.

I tried to reinstall and it works now. Should have tried that before. Sorry.
