I have connected an iPhone to my Win 8 machine and configured Fiddler to with instructions found here http://blog.brianbeach.com/2013/01/using-fiddler-with-iphoneipad.html

So far all seems ok in that when I access a website on the iPhone its logging it and I can see where its going etc. I then need to monitor https requests by that I mean a site in the format of someSite:443.

When I access an app using this mechanism the application freezes and returns an error (cant connect) which I assume is to do with the traffic going through port 8888 - what additional steps do I need to take in order to capture the URLs that the app is hitting?

Hi, Jamie--

http://blogs.telerik.com/fiddler/posts/12-12-21/using-fiddler-with-apple-ios-devices describes the set of steps you should follow to debug traffic from iOS devices.

What is the application you are trying to debug? Some iOS applications use a technique called "Certificate Pinning" to require a specific HTTPS certificate (rather than just any trusted cert) and thus cannot be debugged unless you jailbreak your device and install a tool which changes the certificate validation logic.
