How to reactivate my TRADOS STUDIO 2022 license?

Unable to reactivate my TRADOS STUDIO 2022 license. I am using my travel computer and I deactivated the license on my home computer. Also on my ACCOUNT page it shows as LICENSE IN USE 0 AVAILABLE 1 so should be OK. A message appears UNABLE TO CONNECT TO ACTIVATION SERVER. Internet connection is fine. The link RESET LICENSE described in the YOUTUBE is not there.
