Hello,

I have one VNET with two subnets. One of these have a private web app with a private endpoint. The other one have an application gateway for load balancing and web application firewall. Nonetheless, i have an issue with my backend in application Gateway i have a 403 code issue response from private endpoint. I don't know why I have this issue because private endpoint authorize entries from my app Gateway subnet and my back end pool is configure on MyWebApp.azurewebsites.net.

Do you know how to resolve this issue ?

Thanks for your help and have a nice day,
Kind regards, Kilian GOËTZ.

    I finally found solution of the issue. I forgot to declare a private DNS zone in my private endpoint and declared it into my backendPool. Create DNS private zone is mandatory.
