Windows Server 2019 install product key not working

[Greg Black]

i Have tried both Standard and Datacenter product keys and get errors with both

[#2]

@Brent Forman  I installed Windows Server 2019 Standard version by mistake and activated it waiting for it to come up windows looking on the reboot which of coarse it did not. I then wiped out the raid and all started from scratch and reinstalled windows server 2019 datacenter version on the same computer but it will not activate now? What can I do?

I got the same issue and solved using command line

slmgr/ipk <KmsKey>
slmgr /ato

Example:

slmgr/ipk XXXX-XXXX-XXXX-XXXX
