Root Cause:

Internet access was not allowed on the Host Pool subnet.

Resolution:

Internet connectivity required for WVD VNET as DSC extension need to download from Azure Websites. The DSC extension for Windows requires that the target virtual machine is able to communicate with Azure and the location of the configuration package (.zip file) if it is stored in a location outside of Azure.
