backend returns 404 error

Not applicable

Hi. Let me explain the problem...

When I request the web API directly by Postman without apigee edge microgateway, the response is OK. When I request the web API by edge microgateway, I receive the 404 error as response.

I don't know what it can be. My backend is a c# Web API hosted at Windows 2012 IIS.

It works fine at development environment (Windows and IIS 10), but at testing this problem occurs.

At IIS log file I've found 404 error about favicon.ico request but I'm not sure about it because there isn't favicon reference at api code.

Favicon is a file that browsers request to use as an icon for the tab representing the domain.
