Problem with activating the Gridbox and Forms licenses on new websites

Good afternoon,

I installed a clean Joomla 4 (a higher version is not possible) but couldn’t activate the license for Gridbox and Forms (I initially thought it might be a hosting issue). To check, I created a test subdomain on a completely different hosting with Joomla 5, but the exact same problem occurred there as well.

Could you please advise what can be done about this?

Thank you in advance for your help.
Kind regards,
Tanya
