Cant install/register plugin from Beatsurfer: "Connection Error" (MAC)

hi guys,

im trying to register a new plugin called RANDOM Metal from Beatsurfer.

After pasting the serial, it says Connection Error, like the server is down or Cubase/MacOS doesnt alow it.

I contacted support they say its a connection issue from my side.

Cubase HUB works inside Cubase, i can see the content.
Activity Monitor verifies this, i have in- and outbound trafic with Cubase app.

Not sure what to do now…

Any ideas?

Thanks!
