I am trying to put a WAF front of an azure web app (no ASE). The web app is running with HTTPS (SSL *.azurewebsites.net). I have followed the instructions from this MS document:
Everything went pretty well with my powershell. No probs!
The backend pool is pointing to the correct web app domain ( myapp.azurewebsites.net). And I can see the backend health check is shown as HEALTHY!
I also wonder, in portal when I see the probe blade, the hostname is empty. Which might be intentional as I passed -PickHostNameFromBackendHttpSettings
switch while creating the probe. Just wanted to give more context.
However, if I try to access the site via gateway I receive 404 - page not found.
Can anybody help me finding the problem, please?
