When i capture traffic and try to load something on the page i get logged out...... when i turn capturing off and reload the page everything is fine all pages load fine .... is this a Security issue like a WAF?? a Captcha issue ? or a Cloudflare Issue?  I have tls1.0, 1.1 and 1.2 enabled

Hi,

 

There is an issue with the Progress Telerik Fiddler Web Debugger.

When the system is trying to connect with a websocket endpoint which can't be reached it won't show up in the stream.

It's just completely missing. I would expect that the the websocket should show up in red with a 404 result.

"Fiddler everywhere" has animations.
I hate animations

How can i turn off animations?

I am developing a Chrome extension that activates a proxy. When I enable the VPN and reload the page, the following steps should occur:

1. The Chrome browser makes a request to the proxy.
2. The proxy sends a response with a 407 code.
3. Chrome should call chrome.webRequest.onAuthRequired and provide credentials to the proxy.

However, I don't see any browser interactions with the proxy server.

Is it possible to observe the interaction between Chrome and the proxy using Fiddler?

Is it possible with Fiddler Core to completely replace a response like its possible with Fiddler Classic to do in the "RAW" section if you put a breakpoint before the Response?

Thanks

I have a library that I'm testing out and the .Net Framework 4.6.2 project logs just fine with the normal app.config values.  When I set up the same project using .Net 6/7 I can't seem to get it to capture any packets.

I run netsh command under an elevated privilege command prompt before starting fiddler and then I run the debug mode in VS 2022 and see no entries come across fiddler.  

C:\WINDOWS\system32>netsh winhttp set proxy 127.0.0.1:8888

Current WinHTTP proxy settings:

    Proxy Server(s) :  127.0.0.1:8888
    Bypass List     :  (none)

The only way I can get it to log anything is to enable "Act as a system proxy on startup".  This isn't too practical as then I'm seeing all traffic, which is a lot.

The request is to an https-enabled site.

Is there something I need to do differently in this case?

All of the articles I have read points to this as the correct direction, but they are all 2019 or older.

 

 

Good afternoon!
Someone had a problem that you couldn't connect the Fiedler Everywere to a mobile device. Although the port and IP were entered correctly, but the link to download the certificate does not open. It says there is no internet connection. We tried to download and install the certificate separately, but still feedler does not see the android device
