Rhino 8 licensing wants open port 433

Rhino Rhino for Mac

Hi…,

I’ve tried to use my demo or NFR license for the installation, but failed with the complaint port 443 is not open. (Note: I was logged in at accounts.rhino3d.com, but logged out, because had to use another e-mail address. So in theory port 443 should work.)

What to do next? I’ve searched a little bit in the Mac preferences but failed too. :sob:

Any ideas how to continue?

Thanks

Michael
