KMS Activation Errorr: 0xC004F074

This error occurs for one of the following reasons:
1. The Software Protection Platform Service (sppsvc service) on the KMS host has stopped running.
2. There are networking issues between the KMS client and the KMS host server. For example, TCP 1688 traffic is blocked between the KMS client and the KMS host server.
3. There's an incorrect or old KMS host server record in the Domain Name System (DNS).

1. Therefore we can't control the AWS KMS (169.254.169.250)
2. powershell command Test-Netconnection 169.254.169.250 -port 1688 is successful
3. KMS is set correct via slmgr.vbs /skms 169.254.169.250:1688 and no DNS as no hostnames but IP . These settings were also applied when setting up the instance from the EC2
