SSL Error with browser while capturing traffic

[Mickael]

Hi,

I've a issue with a computer when I launch Fiddler.
Every URL address I want to request is bloqued while capturing is enabled.

If I stop capturing, URL request are passing.

My version is up to date,

I've tried to unistall and clean it, then re-install it without success.

What is strange about it is that I don't have this issue with an other computer with the same configuration, params, and antivirus options.

I've only found one topic about it on google, and the guy solved it with an uninstall (unfortunatly it doesn't help me there :/)

For information, in help > about, it's written 'No Gateway' on both computers.

If you have any information or tips to help me to solve this matter I'ld be very grateful ;)

Hi, Mickael-- How specifically is the traffic "blocked"? Do you see this only for HTTPS traffic or for HTTP as well?

If you see this for HTTP as well as HTTPS, what happens if you try to visit http://localhost:8888 in your browser? Do you have a 3rd party firewall product installed?

When traffic is blocked, what, if anything, do you see on Fiddler's Log tab? Do you have HTTPS Decryption enabled in Fiddler's Tools > Options > HTTPS tab?

Ths thing is that all my traffic url is dericted on HTTPS while capturing is enabled
When I say bloqued, I mean all requests failed to access website, even google.com 
I.E. : while capturing is disable, when I request google, it goes http ; when I enable capturing : it goes https

I've a third party firewall (kaspersky endpoint 10) , but it's the same configuration with the other computer. And even if I disable it, it stills get the same result

In Https tab I've checked the 3 options.

On log tab, when capturing is enable I can see all url requested.

Here is the message I get when I'm accessing http://localhost:8888

I'm so, first first sentence went wrong

I mean :"The thing is that all my traffic url is redirected on HTTPS while capturing is enabled"

Hi, Mickael-- I'm sorry, I'm not sure what " is redirected on HTTPS " means. It might be easiest if you use the Help > Send Feedback link in Fiddler and send me an email that contains a SAZ file (File > Save All Sessions) demonstrating the problem that you have encountered.

thanks!
