Hi,

Based on the exception message I've found this information on MSDN. It seems it is not issue of Fiddler, but rather machine configuration.

As a workaround you can export the Fiddler root certificate to the desktop and trust it manually. In order to do so, please, follow there steps:
1. Open Fiddler, go to Tools -> Options -> HTTPS -> Actions -> Export Root Certificate to Desktop
2. Double click the certificate
3. Select if you want to install the certificate in the user store or the machine one
4. Select "Place all certificates in the following store"
5. Click on "Browse..." and select "Trusted Root Certification Authorities"
6. Click Next and Finish
7. New dialog with "The import was successful" message should appear

I followed the steps suggested & go the 'Import Successful' message - but then got no useful decrypted body text: Instead, I got this message:

"............Encrypted HTTPS traffic flows through this CONNECT tunnel. HTTPS Decryption is enabled in Fiddler, so decrypted sessions running in this tunnel will be shown in the Web Sessions list"

I have also added tls1.1 & 1.2 to the accepted protocols list 

Thanks in advance

I did everything, it still doesn't work

Hello Everyone,

 

Richard, as far as I understand you are now able to capture traffic but it is encoded. If that is the case, try using the Decode button from the toolbar to enable decoding and decompressing the captured traffic.

Keem Star, there is not much information provided for your specific case. Consider describing your issue with step-by-step instructions on what exactly went wrong while importing the root certificate.

Hello I am getting similar issue with both windows 7 and 10. And the awkward part is if I try to re produce it via composer, it gives HTTP 408 if nothing is selected in option. And if there is any option ticked, then it works fine. This seems to be like a bug from your end. How to resolve?

Hey Rahul,

 

It's not entirely clear if you are experiencing the originally mentioned issue (being unable to install and trust Fiddler's CA) or the issue reported by Richard (a specific session not being decrypted). Please provide more details about the specific case you are facing by adding step-by-step details of the actions you are taking and the received versus expected output.
