Windows 10: Cannot activate Windows 10 with digital license after reinstall

Hello,I have a Windows 10 Pro license purchased on my account and it worked fine before i reinstalled Windows. Now after i logged in with my email, it says it's not activated and I tried everything from troubleshooting to entering generic product key. It's getting really frustrating, can someone help?

Digital license

Thats how licensing works with Windows 10, the digital license is attached to your Microsoft Account and makes it easy to reactivate Windows 10 in the event you reinstall it.

Windows 10 Digital License

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft
Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate. You will prompted to enter a product key a couple times through the installation, click I don't have
a key and Do this later.

There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key you already own to
reactivate if necessary. or use the reset function in Windows 10.

How does a Windows 10 'digital license' activate the OS?

source: Activate Windows 10

Does MS digital license 'fingerprint' hardware information during the free upgrade / activation and store it (at Microsoft) , so that the next re-install queries MS for the fingerprint and activates Windows 10?

Thought the disk drive may change, I expect that none of the other fingerprinted hardware will change.
