On the main page of this site there’s a huge white space on the bottom. I’ve read everyone elses topics on this but can’t solve mine. Maybe it has to do with the video background.
I changed the position of your “hero” section to relative instead of auto and it seemed to have fixed the huge white space issue you were experiencing.
I’d try that to see if it works for you. If not, I’m sure there are others that will be able to help!
