Hello,

There seems to be a UI bug (running the latest version of FiddlerEverywhere) where it always says (Paused) no matter it's in on or off:

Mac OS version 10.15.7

I am following the below documentation in order to view the traffic from an Android device. However, my traffic is not being captured in Fiddler and when I have the manual proxy settings enabled then my device appears to block any traffic. Could you help please? Are there any other instructions that I can follow?

https://docs.telerik.com/fiddler/configure-fiddler/tasks/configureforandroid#configure-android-device

Thanks. 

Hi i'm using fiddler classic to analize performace of a client/server application (client winform and server on Azure .Net 4.8).

Comparing fiddler trace on 2 different PC (home pc and work pc) i notice a very long delay beetween GotRequestHeaders and ClientDoneRequest on work pc.

For example:

Home PC (equal time):

GotRequestHeaders 21:39:55.294
ClientDoneRequest 21:39:55.294

 

Work PC (0.4 difference):

GotRequestHeaders:    12:46:54.730
ClientDoneRequest:    12:46:55.109

 

Do you have any idea what could be causing this problem?
Could be an antivirus/Firewall/some software?

 

Thanks

 

I'm trying to set up environment where I can display HTTP/HTTPS traffic coming from/to the android device on my Windows 10 machine. I followed this manual for Fiddler Everywhere https://docs.telerik.com/fiddler-everywhere/traffic/configure-android However I can't seem to be able to access the Proxy from my phone.

Root certificate has been installed/trusted.

I enabled the proxy in "Settings"

Live Traffic is enabled and shows all requests for that Win10 machine.

IP address of the wireless interface of the Windows device is 192.168.8.110

I'm using Samsung S21 with Android 13.
I then set up this IP and 8866 port as proxy for my WiFi connection on the Android phone and navigated to ipv4.fiddler:8866 But it constantly responds with ERR_TIMED_OUT and keeps reloading. Also nothing from the mobile device is visible in Fiddler Live Traffic on Windows machine. I wasn't able to find a related topic on the forum. Any help would be greatly appreciated.

 

Great, I installed the fiddler update. Now I can no longer decrypt https client traffic while debugging.... 

"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel"

 

 I had the fiddler cert trusted before and didn't get a prompt to trust it when enabling https decryption.

 

So I uninstalled Fiddler and removed the certs.  Then reinstalled and I get the prompt but my apps are still faiing....

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

 

  

 

 

HI team.

we are using Fiddler core and wanted to have a small UI for it. wanted to check if Fiddler Core works with MAUI for mac and if there is some documentation. currently we are able to run it is net 6 but not in MAUI

also if there is any other technology that can be used apart from MAUI then it would also help

 

Thanks

I searched the web and found the .NET 'File.Open' instruction, but I have not been able to successfully use it in my script.

I am looking for something like this...

var content = File.Open('path/filename.txt');

This code is just an example, it does not work.

Thank you!

I am using the following code to serve a local HTML file when the URL of a web request contains a certain keyword.


Instead of a local file, is it possible for Fiddler to reply with a web page hosted on a remote server? Something like this...


Thank you!

The live traffic pane is showing a spinning animation as if it is loading something. It keeps going like this in a loop.

Please see attached image.
