"Video format not supported" with Moodle

I have a problem with my course, all the videos could be uploaded correctly without problems and they were seen properly. But, for some time now, every time the page has a lot of traffic, the videos are demaged with "video format not supported"

What we do when this happens is delete the video and re-upload it and it immediately fixes itself. But we have to be there 24/7 for any eventuality, because users are having a bad experience.

The platform we use is Moodle and that the videos are uploaded in MP4 but converted to interactive videos.

Happen in all wrowser: Chrome, Firefox, Safari etc

Happens in mobile and desktop

 Version of H5P: Marco H5P v1.24 (h5plib_v124) 

We don't know what to do, how we can correct it.

We only know that when the site has low activity nothing happens, but as soon as it has a lot of traffic a video is damaged. I clarify that not all are damaged at the same time, two, theree or less.

Hopefully they can help us with a solution
