Browser SSL Errors - Your connection is not private

Hi there, having an issue getting to certain websites.  Profile is very simple... lan-wan, all, all, always, nat enabled, only security profile is ssl "certificate-inspection".  No content filtering, dns, antivirus, ips etc.  Regardless of the browser, we get your connection is not private.  NET::ERR_CERT_COMMON_NAME_INVALID.  Try to import the fortinet certs into the trusted root authority but error still persists.  Tried both flow and proxy based inspection.  Any thoughts?
