    I'm using Fiddler v4.6.2.32002 under Windows Server 2008 R2

    Protocols set in fiddlers settings:


    Certificates generated by CertEnroll engine

    I'm trying to access and capture its traffic using Chrome (version 52). I receive ERR_CONNECTION_RESET when trying to view shopping cart while fiddler is running. I get similar result in other browsers: "This site can’t be reached The connection was reset." in Opera for example.

    Fiddler Log:

    13:07:38:5647> HTTPS handshake to (for #1) failed. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. < The token supplied to the function is invalid<br>Win32 (SChannel) Native Error Code: 0x80090308

    I tried:

    resetting fiddler's certificates, changing protocol list. No success.

    I need to capture and decrypt the traffic.

    What other steps should I do or what info provide?

    Sorry about the late reply.

    Do you have any third party encryption software installed? It looks like Windows cannot access the certificate private key. Normally regenerating the certificate could help if it's a one time glitch.

    You could try typing prefs set fiddler.certmaker.bc.Debug True in the quick exec box and check the log for more info.
