My site stoped displaying mp4 files


I had simple 7Mb embed video displayed just fine until this week.

Do I need to enable large-media features or is there anything else I am missing?

it says: Media resource could not be decoded.

But I can right click and open it in a new tab and the video file plays just fine.

<video class="embed-responsive-item" autoplay="" muted="" loop="" controls="">
<source src="/videos/band-horses-video.mp4" type="video/mp4"></video>
