Hi,

I try to capture my traffic from my App running on an android device (VPN necessary) using Fiddler on Windows 10. The App is using netstandard2.0. So I follow the instruction of this:

   https://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/DecryptHTTPS

   https://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureForAndroid

   https://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureDotNETApp

 

It works all fine without using VPN. But when I activate VPN Fiddler doesn't capture anything of my android device. Any idea?

Simeon, does your response mean that it is NOT POSSIBLE to capture with the VPN present?  Thanks.

ey Herb,

 

Fiddler works with VPN in the case where the VPN and the FIddler proxy are on the same machine. However, it won't work for a remote PC/device like in the case described by Matthias (where the remote is the Android device with VPN, and Fiddler is working on another network).
