Error adding WebApp to VNET

Question

Ive been fiddling with this for a few hours now and getting nowhere.

1. I have a VNET with multiple subnets
2. The VNET has a Site to Site connection to an internal network
3. I have a Web App running fine
4. I need the Web App to access an internal SQL Server on one of that Subnet in the VNET
5. When I try to add the subnet under VNET Integration in the Web App I get the error

"Configure VNet to the app
An error has occurred."

There is no explanation anywhere as to what is causing the error.

Answer 1

@SaiKan Web App Vnet integration requires a dedicated subnet. All subnet requirements for Vnet integration are described in this link https://learn.microsoft.com/en-us/azure/app-service/overview-vnet-integration

Please go through the documentation and verify whether your chosen subnet meets those requirements.

Thanks!
