I am still facing this issue. The problem I am having is if I got to mysite.com the page won't come up. I have to type in the https://mysite.com in order for the site to work. I have tried to use a listener on port 80 and then the backend redirect to a HTTPS listener but it doesn't seem to work. I have also tried both 80/443 as the listener and the backend redirect to an external site using https://mysite.com but that didn't work either.
