Google iOS App Not Working with Fiddler

Greetings,

I'm currently not able to use the Google iOS app with Fiddler and I can't seem to locate the source of the problem.

I use Fiddler extensively and this is the first app that I've encountered this particular issue.

The relevant versions are as follows:

iOS 10.2.1 (iPhone 6)

Google iOS App 23.0.147401934

Fiddler 4.6.20171.7553

.NET 4.6.2

Windows 10.0.14393.0

Any insight or suggestions regarding this would be very helpful, thanks!

pple added an additional step to trusting third-party root certificates that is not (yet) included on the help page: http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureForiOS

After installing the FiddlerRoot certificate, one also needs to go to Settings -> General -> About -> Certificate Trust Settings and manually enable full trust for the FiddlerRoot root certificate, including accepting a dialog that says that this will allow a third-party to eavesdrop on all your communications.

What do you see in the Fiddler trace as well as in the app itself?

I am starting to encounter issues where some domains are not working properly with the iOS cert, but others are decrypted just fine. For those apps, Fiddler breaks the app when I enable it as the proxy on the iPhone. For example the (Free) GasBuddy app - urls to domains such as media.lowermybills.com are intercepted by Fiddler and decrypted, but Fiddler cannot seem to deal with api.gasbuddy.com or reports.crashlytics.com
