Video Controls Disappear and Error Loading This Resource

On initial entry onto the page, you will see the video controls and they disappear and "Error Loading this resource" is displayed at the top of the player.

If I refresh, and click on the "Play" button as soon as I see it, I can get the video to display (sample.mp4), but If I hesitate and don't click on it fast enough - error and no more controls available.
