Recently Microsoft stopped all phone activation lines (even the last few ones that were still working), and is now redirecting all customers to aka.ms/aoh

But when doing the phone activation there, sometimes this error shows up for some people



There is nothing wrong with the Installation ID itself, if I do the activation via the CID tool from kichhoat it provides me with the CID with no issues.

Does anybody know what could be causing this issue? I didn't encounter it until 2 days ago..
