Hello,

Whenever i'm opening the "Fiddler 4", it's showing me below warning, and after clicking OK, the application opens:

Could anyone please let me know the issue here?

Well, once it's open, I'm getting error: " Fiddler - Gateway Connection Failed." while trying to pull the image from docker.

Hey,

So currently I am coding a Program and want to use the CertMaker.dll as embedded resource and want to load it from resources so I don't have to extract it to the same folder as the program i am running. This also works, it creates the certificate as it should but it doesn't fake the requests then.

I cant use the CertMaker.dll as Resource. Is there any workaround?

Hello


I'm using fiddler to test thick client application network request with IBOSS proxy , but seems fiddler is not able to intercept requests as IBOSS is continuously changing proxy with its background service.  Fiddler is showing The system proxy was changed, Click to reenable capturing.  

My System proxy is point to .pac file of IBOSS. 
Fiddler gateway tab is set to Use System Proxy.

I've tried several options like  changing gateway option to use IBOSS .pac file and all, but none of them worked.

any help would be appreciated.

Thanks

hi guys, i very tks all to make this software

but when i config proxy (IP and Port show in picture) in my fone, i just can access to my VPS address, can not access the internet, just show Connection not Private

 

show how can i config HOST: Localhost to access internet

 

tks very much, sorry for my English, i'm not good  :( 

hi, 

I'm trying to understand how to solve a problem i'm having, I hope someone with more experience can enlighten me. 

I'm developing a small app wich does some api call via WinHttp.WinHttpRequest.5.1 . I'm having trouble with a particular get request: the result i get shows some strange characters instead of accented characters. However when I use Fidler to do the seme get request (headers and everyhing are exactly identical) the result i get is correct. the response  I get on Fidler has the characters in the correct way in raw, in text view and all the other tabs except for hex view!
in the hex view tab of the response, the text that i can see in the right column is exactly showing in the same wrong way as I see it in my program.

I would like to understand how the text shown in the right column of the hex vie tab of the response is treated/transformed by Fidler so as to become the correct text shown in the other tabs. If  i could understand that, I think I could apply the same tranformation on the wrong text that I get in my app.

thanks for the help

I have Windows 8.1 installed on my computer and regularly use Fiddler to capture web traffic.

Recently, however, when I open Fiddler and it strats to capture web traffic, my Internet connectivity dies.

The error I get when I open IE is "the proxy server isn't responding." In Chrome, I get "Could not connect to proxy server" with the following error: Error code: ERR_PROXY_CONNECTION_FAILED.

Fiddler doesn't even capture any of the requests going out. The weird thing is that Fiddler was working ok just some days ago and nothing was recently installed on my system.

Searching the Internet for 5 hours, trying everything, and no effective response.

This also had no effect: http://www.telerik.com/blogs/fiddler-and-internet-explorer-11-on-windows-8-1​

It seems that the proxy server created by Fiddler is simply not attending to any traffic.

If I close Fiddler or disable the capture mode my internet come back to normal.

Uninstall and reinstall Fiddler does not solve the problem, neither restart Windows.​

Why is Fiddler having this problem, and how can I fix it?
