Hi @teklemis
Based on your request to Assign App Service domain to Azure VM or Azure Storage
Azure VM from App Service in virtual network by private DNS
After your app integrates with your VNet, it uses the same DNS server that your VNet is configured with. By default, your app won't work with Azure DNS Private Zones. To work with Azure DNS Private Zones, you need to add the following app settings:
WEBSITE_DNS_SERVER with value 168.63.129.16
WEBSITE_VNET_ROUTE_ALL with value 1
