I am having trouble with a specific financial services provider; every time I try to visit myvisaaccount.com to check my card balance etc, I get the dreaded Chrome red strikethrough https and x-ed out padlock, with dire warnings about an insecure connection. If I try Safari or Firefox I get different visuals but the same message: invalid security certificate.
However, tech support for VISA does not see this problem from their own home or office computers.
So I am trying to find out why my OSX Lion laptop hates this web site so much. I have got into the Keychain Access tool and I have no personal certificates: empty list. System (and Root) Certificates are all up to date, with no anomalous descriptive text. And yes, my system date/time is correct and I am in the right time zone, and I am getting my date/time from Apple N America timeserver.
I am thoroughly out of ideas and very frustrated with this problem. What more can I do to diagnose or fix it?
