Help with Azure Function Deployment Error 403

Hey everyone! I've hit a snag trying to deploy my Azure function app. My local machine is connected to the virtual network through a VPN gateway, but when I attempt to deploy from Visual Studio Code, I keep getting a 403 access denied error. I've configured the Azure function within a private subnet using VNET integration, and there's no public access allowed. Can anyone help me figure out what I'm missing? Thanks a lot!

It sounds like you're using VNET integration, which is great for outbound connections, but for inbound access to your Azure function app, you'll need to set up a private endpoint. Since you've disabled public access, that might be why you're facing the 403 error. Make sure to check that!

TechWhiz123: Thanks for the info! So you're saying I need a private endpoint for my Azure function as well as the VPN gateway?
