Fiddler on AWS EC2 not responding on public IP

[Andrew]

Hi

trying to monitor my phone traffic via a fiddler running in windows 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 ://<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  listen to the public 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)?
