Conflict moving Windows 10 Digital license linked to Microsoft Account

I have windows 10 with a digital license that I got from upgrading from Windows 8.1 to Windows 10 during Microsoft Free upgrade time. I had it linked with my Microsoft account and the computer is showing up as my device on the Microsoft website. Then I took the HDD and the SSD from old computer to my new one. Now the website shows both computers as my devices.

But now when I try to activate the windows on the new pc while being logged in with my account, there are in fact no devices showing up which I could be activating windows from this I can’t activate windows on my new pc. Also most of the time I try to do this the servers are down.

Strangely enough, when I connect the HDD and SSD back to my old pc, it is activated.

Please help me resolve this issue.
