    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

    Regards,
    Alexander

    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
