When my device and system are connected to VPN, no traffic is captured in Fiddler. Do we need to perform any additional settings in order to capture the traffic while connected to VPN.

 

Here are few configuration details : 

- "Monitor all connections" checkbox is enabled

- No traffic is captured when both mobile and desktop are connected to VPN

- Traffic is captured when only desktop is connected to VPN. But unable to connect to VPN over mobile once Fiddler is running.

 

Thanks!

When attempting to contact the remote server we get error:

The initial contact works:

I am able to capture the request and response of my application. Now I need to save it in readable format (SAZ/Txt) which I am not able to accomplish

Hi - When I try to create, or import an encrypted save file, or try to open an encrypted save file, I receive an error: "Value of 'null' is not valid for 'stream'.".  It does not appear to break the process, it still asks for a password, it still seems to save the file, and it still seems to import the file.   I am running version v4.6.3.50306.

Here is my layout to start.

 

I am trying to get www.mysite.com/blog/ to rewrite to blog.mysite.com.

Both of them are separate IIS Websites on the same server.

 

I discovered that the way to do it was ARR.

 

I have set it all up and it works, but here is the problem.

It only works when I set the Proxy Chain to localhost:8888 and fiddler is running.

But otherwise, it does not work.

I don't want to leave Fiddler running all the time.

 

What can I do?

Hello,

I'm trying to capture remote traffic of an iOS App but unlike other Apps this one gives a problem.

When i use the app with "Decrypt HTTPS Traffic" enabled, the app simply says "Network Unavailable". I tried using both the root certs (MakeCert and CertEnroll) but still i have the issue.

But i have tried various other apps and they never had an issue like this.

Protocols - <client>;ssl3;tls1.0

Hi everyone. Basically the issue im having is that I want to capture and decrypt traffic from a program. The issue is that nothing related to it shows up on Fiddler.

Yes I already checked the filters, everything is fine and also tried removing and reinstalling the certificates. The odd part is that Net-peeker 3.50 can capture the packets but of course I can't decrypt the traffic.

Any suggestion will be greatly appreciated.

Thanks.
