    Hello @KRISHNA, CHOPPADANDI VAMSHI

    For Private Endpoint on Azure APP Service You must set up a private DNS server or an Azure DNS private zone. For tests, you can modify the host entry of your test machine. The DNS zone that you need to create is: privatelink.azurewebsites.net. Register the record for your app with a A record and the private endpoint IP.

    Have you followed the steps to create the Private Zone ?

    Aso here are some usefull limitations - info :

    • When you use Azure Function in Elastic Premium plan with private endpoint, to run or execute the function in Azure portal, you must have direct network access or you receive an HTTP 403 error. In other words, your browser must be able to reach the private endpoint to execute the function from the Azure portal.
    • You can connect up to 100 private endpoints to a particular app.
    • Remote Debugging functionality isn't available through the private endpoint. The recommendation is to deploy the code to a slot and remote debug it there.
    • FTP access is provided through the inbound public IP address. Private endpoint doesn't support FTP access to the app.
    • IP-Based SSL isn't supported with private endpoints.
    • Apps that you configure with private endpoints are only accessible through private endpoint from clients in subnets that are configured with the Microsoft.Web service endpoint.

    In case this answer helped you resolve the issue kindly mark it as Accepted ! Otherwise provide some onf on the Architecture and the community will follow up to assist !

    have a nice day !
