HaProxy - Http and SSL pass through config

I've currently got an HaProxy LB solution in place and everything is working fine however we are having an issue with a very few clients who cannot get to our site via HTTPS (SSL) they can browse our site in Http but as soon as they click on an absolute HTTPS link they are taken to our home page instead. Wondering if anyone can look at our config below and see if there's something awry. I believe we are on HaProxy 1.2.17
