Windows Activation failed in EC2 instance

I am using Windows Server 2019 Datacenter in EC2 Instance. Now I received the following error: "We can't activate Windows on this device as we can’t connect to your organization's activation server. Make sure you're connected to your organization's network and try again. If you continue having problems with activation, contact your organization's support person. Error code: ‘OxC004F074"

For your kind reference, I also attached the image for the same.

Kindly help me to activate the windows.
