Lightbox Button Does Not Play Video on Click

There is an issue with Webflow that I just cannot figure out: a lightbox video will not play on the published website: https://www.behanceblueprint.com

On the homepage of my website I set up a Lightbox Link and when you click on the “Watch Trailer” button a Youtube video is supposed to play, The Behance Blueprint Course - YouTube

This functionality works in preview but not on the published website. I have tried a YouTube video and Vimeo video as the lightbox media link and neither work.

I’ve seen this same behavior work on other Webflow pages but it is not working on mine.
Example: Web Design: Becoming Professional | Comprehensive online course to learn web design
