Azure Front Door Visual Studio Remote Debugging

Question

When connecting to my Azure Web App protected by Azure WAF/FrontDoor, I cannot connect to the debugger, it seems like inbound port 4024 is blocked on the WAF/FronDoor. Remote debugging is enabled and outbound ports are open on the dev server. Any idea if this should be working or how to get this working?

Thanks.

If you are using 64-bit you must enable the port 4025. For 32-bit you must enable the port 4024.

I also had this problem. I solved it by changing the Platform from 32-bit to 64-bit. Go to App Service -> configuration -> General Settings. Now change the Platform from 32-bit to 64 bit.
