Background video hosted on AmazonS3 plays in design view but not when published

Hi guys

Just managed to figure out how to host background video on AmazonS3.
Everything is working well on Design mode, but the screen is black when the website is published.

Any idea what the problem might be?

Many thanks in advance.
