Azure Windows Server 2022 VM Activation Issue

Question

Server 2022 Datacenter Azure Edition VM was originally activated when built on 2/3/2022, but now will not activate:

slmgr /dlv output:

slmgr /ato output:

VM has no issues pinging kms.core.windows.net:1688

Other Server 2022 Datacenter VM's are all activated, all of the VM's (including the 1 that will not activate) are on the same virtual network, same resource group, going through the same firewall:

Local firewall is off on the VM having the problem as well as all other VM's that are activated.

Answer 1

My first recommendation would be to go through the guide for Troubleshooting Azure Windows virtual machine activation problems
Azure uses different endpoints for KMS (Key Management Services) activation depending on the cloud region where the VM resides. When using this troubleshooting guide, use the appropriate KMS endpoint that applies to your region.

One of the customer in this post shared what worked for them :
If the VM date/time was set to UTC, activation was successful. However, if date/time changed back to local time, activation warnings would commence again.

Another customer resolved it with the help of these commands:
slmgr /upk --> To uninstall existing product key
slmgr /ipk --> NTBV8-9K7Q8-V27C6-M2BTV-KHMXV
slmgr /ato --> To activate
slmgr /xpr --> To check activation expiry date.
