We are finding a number of outgoing request in Failed request trace. The request is to the same web server, but via LB. Since the LB is listening at https, not http(port 80 is not opened in firewall), the request is failed. As per the failed request trace, the request is originating from the same app pool.
We did a global search for this URL in the source code, but could not find anywhere hardcoded. Not in the web config too.
The failed request xml shows x cluster ip a public ip
How do we search for the origin(code) of this request?
. I believe this call will block the resources as it also throws exception in Windows event.
