I thought , or found out . the problem is server. Or the system server wouldn't recognize or accept such upgrades or Windows 11 Pro. I had similar problems occurred when downloading or installing server or apps by saying ''Unknown Publisher''

Did you buy the licence from the windows store or the Microsoft website.
Did you receive an email after the purchase containing the product key?

Could you describe what you mean by your product key doesn't work?
Do you get any error codes? Does the enter product key page not work?
More detail will help in situations like this :)
Hope to hear back from you.
