Hi Guys, I have recently downloaded Fiddler. The program itself is great but whenever I close it and I start epic games then there is always a mistake that is not Internet connection. But as soon as I reopen Fiddler, epic games has a connection. Maybe you know what I have to do so that I can start epic games again without fiddler? Thanks in advance

Launching and closing Fiddler on Mac prompts for admin authN as it tries to configure the network(WiFi adapter in my case.)

I assume it's doing this to set the proxy. Does anyone know how to give Fiddler rights to make these changes whenever necessary, without the authN prompt?

Thanks

What I am wanting to achieve I think can be done with Fiddler Core, but I am not really a developer, I know enough to modify code and compile it but not to start from scratch.

This is what I want to achieve, I want to listen for a specific URL and POST value, then change the response (which I can do in Fiddler no problem), I want to then compile these settings into a standalone exe with no user interface or options, so i can simply doubel click and have it work on any pc. Since this would seem like a fairly standard use of Fiddlercore, is there a sample project I can download to start me off?

Slightly off topic to the above, rather than wait for the response from the server, can I just respond automatically (maybe add some latency first) and drop the real response if/when it comes?

 

thanks!

 

 

Hi,

 

I'm trying to use Fiddler Everywhere on macOS Mojave (10.14.4) and the proxy does not appear to enable after clicking the Capture button.  When I initially installed Fiddler and opened it, I was prompted for my password (but it still did not appear to be capturing any networking traffic).  I also got the password prompt the first time I closed the app.

 

I have since re-opened the app a few times and tried to click the Capture button, but nothing happens.  I also no longer ever get any password prompts (either on app open/close/capture button click).  I've tried to uninstall + reinstall the app as well with no change in behavior.

 

I also tried to run the app using sudo (using the following command):
sudo /Applications/Progress\ Telerik\ Fiddler.app/Contents/MacOS/Progress\ Telerik\ Fiddler

 

Please find the logs (electon.log and netcore.log) attached.

 

Any idea what might be going wrong?

Thanks

I'd like to be able to decode/inspect websocket messages (messages are 20-byte binary) so that each message can appear in a human readable way.  We basically just want to extend/add a custom websocket inspector which will show the selected message after it's been custom "decoded".  I have purchased Debugging with Fiddler Second Edition, but don't see any guidance for implementing a custom Websockets inspector.

Any guidance would be greatly appreciated!

Thanks!

When connecting my phone to fiddler, I am able to receive traffic. However, which host do I select to filter so fiddler only shows traffic from my phone? Both AppleDeviceService and YourPhone did not work for me.

Reinstalling without keeping settings did not help. I'm guessing I have something really huge/corrupted in the Composer history. Which file / registry key should I delete?

Thanks!
