    I am receiving an error from Fiddler when attempting to decrypt HTTPS traffic from a specific site.  Other HTTPS sites seem to be working Ok.

    The error is "fiddler.network.https> HTTPS handshake to login.nbnco.net.au"

     

    URL : https://login.nbnco.net.au/portal-login

    Fiddler Version : 

    v4.6.20171.14978
    Built: Tuesday, 21 March 2017
    64-bit AMD64, VM: 110.0mb, WS: 90.0mb
    .NET 4.6.2 WinNT 6.1.7601 SP1

    HTTPS protocols being used : <client>;ssl3;tls1.0

    Browsers used :

    Chrome Latest - Version 58.0.3029.96 (64-bit)

    Internet Explorer : Version 11.0.9600.18638

    Fiddler Log :

    11:46:38:4535 fiddler.network.https> HTTPS handshake to login.nbnco.net.au (for #1136) failed. System.Security.Authentication.AuthenticationException A call to SSPI failed, see inner exception. < The message received was unexpected or badly formatted

    Win32 (SChannel) Native Error Code: 0x80090326

    Can anyone tell me what is happening here?  And any steps I can take to rectify?

    I have already followed other advice I have seen regarding Resetting Certificates, and restarting Fiddler.

    Much thanks!!!

    Chris
