Hi,

I've checked your page, the video you've inserted is loading properly without any issue.

By default, WordPress doesn't support insert Facebook Video, please try to use Vimeo/Youtube/DailyMotion or upload video directly to your hosting instead.

In case if you want to use Facebook Video, please read this document here: https://www.wpbeginner.com/wp-tutorials/how-to-embed-a-facebook-video-in-wordpress/
