    Using Deploy a zero-trust network for web applications, here some things to check from a connectivity standpoint.

    • Verify that Service Endpoints and VNET_ROUTE_ALL is enabled to allow VNET traffic through.
    • Verify the configuration of the private endpoint.
    • Start by pinging the IP address from your VPN connection. If successful and the DNS name isn't working correctly, check the A and CNAME records in Azure DNS.
    • Check any Azure Firewall or Network Security Groups (NSGs) that is configured that could be blocking traffic.
