Hosted video not playing | WordPress.org

I just installed the pro version.
Using Elementor, so I added the short code on the product page template.
Uploaded a video to my wordpress Media and added to a test product. Thumbnail is shown, but video is not playing.
Tested it with a Youtube video, and that worked, but the self-hosted one didn’t.

What can I do to fix it?

Cheers.
