    This error message suggests that Fiddler is unable to create root certificates.

    Please perform the following steps:

    1> Tools > Fiddler Options > HTTPS.
    2> Untick "Decrypt HTTPS".
    3> Click Remove Interception Certificates. (Accept all prompts)
    4> Retick "Decrypt HTTPS".

    What, if any, content do you find on Fiddler's LOG tab at this point?

    The "=> (0)." text indicates that creation of the root certificate was successful. What happens if you subsequently visit a HTTPS site at this point?

    I'm not sure where the text "Fiddler free web debugging proxywww.fiddler2.com" came from, as this text is not ever logged by Fiddler itself.

    I have the same issues running on a Win7 Fiddler v 4.4.9.2
    I've also tried to turned off the Capture and removed the certificates. Just no HTTPS any where?!?!

    Unfortunately, I don't know what "Just no HTTPS any where?!?!" means precisely.

    First, please update to the latest version of Fiddler.

    Next, in Fiddler, click Tools > Fiddler Options > HTTPS. Untick "Decrypt HTTPS traffic." Click "Remove Interception Certificates." Accept all prompts to remove certificates.

    When the process completes, Close Fiddler.

    Restart Fiddler. Retick the "Decrypt HTTPS traffic" box and accept all prompts to trust the new certificate.

    If things aren't working, share the Complete contents of the LOG tab as well as information about what you're trying to do (e.g. "Use Internet Explorer to visit https://google.com and see the traffic in Fiddler").

    Thanks,

    My Fiddler is now 4.4.9.6
    cleared the Interception certificate ( only 1 prompt )  and closed fiddler
    Restart and clicked the box to decrypt
    Same log entries
    I get the same results when browsing in IE .
    The filters tab has nothing on.


    IE 11, open the https url.    I only get the 200 response Tunnel to

    This is a CONNECT tunnel, through which encrypted HTTPS traffic flows.
    Fiddler's HTTPS Decryption feature is enabled, but this specific tunnel was configured not to be decrypted....

    Surfing in Chrome doesn't record anything? even if I pick the chrome session.

    Tried to start from the Composer and that worked! but I need the to get recordings of my 2nd and 3rd steps.  No sure how to do that from the composer??

    If you send me a SAZ file (Help > Send Feedback), I can probably help.

    The message you saw suggests that you have decryption disabled on a per-process or per-host basis inside Tools > Fiddler Options > HTTPS.

    Hi, just want you let you know, that I had problems with chrome and the latest Fiddler4.

    My Root Cert could not be found. I found that solution: http://superuser.com/questions/145394/windows-7-will-not-install-a-root-certificate

    Now it works great!
