I'd like to see my requests grouped like requests "collect/" to appear at the top of my monitor or saved to some folder. Is it possible?

The following page loads ok when not using Fiddler Classic as a proxy...

https://www.investing.com/currencies/eur-usd

But if I use Fiddler, the chart on the page will not load! I checked everything and the problem seems to be related to the fact that some resources needed by the page above do not load, and that is because Cloudflare is returning a captcha question instead of data. One such resource file is this, for which I am always getting a captcha when using Fiddler (it works ok otherwise):

https://api.investing.com/api/financialdata/table/list/1?fieldmap=general.slim

Is there any way to fix this, please? I would like to pass all the traffic through Fiddler, and have the page load ok every time.

My Fiddler is not set to make any kind of changes to the page headers, or its content. So I guess Cloudflare is using other ways to detect when traffic is not coming directly from a web browser.

Thank you!

Hello. I use Fiddler classic. I have a problem please support. When i enable fiddler i can't access this site i get below error. How can I recover from this error? I am attaching the error screenshot.

[Fiddler] The connection to 'zone.game' failed.
System.Security.SecurityException Failed to negotiate HTTPS connection with server.fiddler.network.https> HTTPS handshake to zone.game (for #75) failed. System.Security.Authentication.AuthenticationException Ошибка вызова SSPI, см. внутреннее исключение. < Получено непредвиденное сообщение или оно имеет неправильный формат Win32 (SChannel) Native Error Code: 0x80090326

 

Hello . I use with fiddler Everywhere. When  I install the software have the problem is
Fiddler login problem is like:
Http failure response for https://identity.getfiddler.com/oauth/token: 0 Unknown Error

and request back to sign in 

In the CONNECT response frame, we have the "Client Certificate" so we know there was a CERTIFICATE REQUEST made by the server as part of its SERVER HELLO response. What I would like to know is what DN(s)/CN(s) the server sent down with the CERTIFICATE REQUEST. I have not been able to find any references to pull this out of the SERVER HELLO response.

  

Environment:

FiddlerCore: v5.0.1

.Net: v6.0

Issue:

I've written a fiddle script to send another request to get the necessary info to proxy the original request via FidderClassic. It works fine with the tls1.2 protocol. But when I try to use FiddlerCore to do the same thing, I got the 502 error again(the error occured when I use FiddlerClassic without tls1.2 protocol).

Is there any insights for this issue? Thanks

 

Environment:

FiddlerCore Version: v5.0.1

.Net Version: .net6.0

windows： win11 22h2

Issue

My requirement is when I get the specific request, I need to send another request to get some extra info and then modify some parameters of the original request. I wrote a fiddler script to achieve that and it works fine by Fiddler Classic when I set the TLS1.2 for Https options.

But when I try to use FiddlerCore to do the same thing, I got the 502 error.

I followed https://www.telerik.com/blogs/fiddler-and-modern-tls-versions to set the protocols of connection to support the tls1.2, but it doesn't work!!

Is there anyone can help me figure out what should I do to to resolve this issue
