Hello Navid,

I need more information in order to help you.

Are you trying to capture Android or iOS traffic with Fiddler on your PC? Here is described how to capture Android traffic, and here - iOS traffic.

What VPN are you using. Is it set up on your mobile device or on your PC, or on both of them?

Hi Navid,

You may try configuring Fiddler on the machine that is capturing the VPN traffic to use the same VPN Connection as the iPhone. See the Monitor RAS, VPN or Dialup Connections for adding a VPN connection to Fiddler.

Note that this may be dependent on which VPN provider is in use and may not work.

Please give this a try and let me know the results. Thank you.

also yes its difference between providers,like one vpn have a option inside with this "let debug http" which make u to while u using that vpn,can capture the http by fiddler too but its only for android version not ios (this is why i was looking for a way)

Hi Navid,

Thank you for providing the additional information. It sounds like this is an issue with the VPN provider or this could also be an iPhone issue where it will not allow capturing the VPN traffic. 

In either of the above cases, these are platform-level issues and there isn't much that Fiddler can do to alleviate them. For more information on platform-level issues with iOS and Android see the Using Fiddler with iOS 10 and Android 7 blog post.

I hope the above information is helpful. Please let me know if you need any additional information. Thank you for using the Fiddler Forums.
