Dear team,
We configured App Gateway with WAF in front of the APIM.
We are getting 502 Bad Gateway exceptions when invoking the App Gateway. We configured listeners, backendpool, backendsettings and routing rules but not able to process the request from public address
Could you please help how to resolve the issue?
