    TCP_443 is just performing a 3-way handshake on port 443. HTTPS performs 3-way handshake followed by SSL handshake. If TCP_443 works, it is fair to conclude that route to the pool member exists and the pool member has port 443 listening. If HTTPS is failing, I would check to make sure if there are any issues with the cert utilized.
