    Hi Chakuttha,

     

                    They are trying to use redirect based authentication on explicit proxy which will not work for the CONNECT requests as it won't take redirect as a response. Once the SSL Interception is through, they a redirect based auth will work. The error in policy trace is clear on this

     

      EXCEPTION(configuration_error): Authentication failed because of a configuration problem
      Last Error: Cannot use origin-redirect or form-redirect for CONNECT method (explicit proxy of https URL)

     

    Ref: https://support.symantec.com/en_US/article.TECH242876.html

     

                If they are in need of such redirect based auth, they will have to make sure that the first request is HTTP and use a surrogate based auth mode like "Origin-IP-Redirect" to get it authenticated once during the surrogate refresh time.

    Hi Chakuttha,

     

                     The issue only happens when the first request is HTTPS Connect and proxy can't redirect it for authentication. Taking policy trace could give away the reason on why it is not happening on other branchs.
