    Hi

    Im trying to monitor my phone traffic via a fiddler running in windows aws EC2 machine.

    I setup Fiddler on a windows machine in EC2, I have enabled allow remote connection and I have open port 8888 on windows firewall and AWS firewall.

    I point my phone network proxy to public IP for that machine and the right port.

    When I open http://<public ip>:8888 on the phone, it never returned with the Fiddler echo page.

    I noticed that in Fiddler there is a traffic coming in but it never complete and seems duplicated (loop).

    I suspect that the fiddler echo page doesnt listen to the public IP, and only private IPs.

    Can someone guide me where can I change that setting or what step have I missed?

    Hello Andrew,

    I noticed that in Fiddler there is a traffic coming in but it never complete and seems duplicated (loop).
    Is it possible that the machine is behind Network Address Translation (NAT)?
