Not workong with SSL

Hello,

I had to install “WP Force SSL” on a website and lost the popup. It seems like the latest support question on this is outdated, and the field for specific URLS says it shouldn’t have https. How can I get this to work on https?

Here’s the site, my client would like their trailer to play as soon as the site loads.
