Unable to activate Katalon 6.3.3 on a new windows system

Using correct username and password I am not able to activate Katalon 6.3.3 on a new windows system.

Hi
I understand that Katalon authentication servers for older version have already been switched off, therefore no new activations of version 6.x or below software can occur. See thread:
