Error Loading this resource with self hosted videos

How are you adding the video to the post? Are you selecting it in the media gallery? Also, what is your WordPress version?

Hello again,

I found an answer to this problem: https://wordpress.org/support/topic/chrome-and-firefox-wont-load-header-video-in-twenty-seventeen-theme/

The problem is that the different navigators, and even the different devices, doesn’t have the same rights or capacity to run different video formats. So you need to encode your video file following the compatibilities you need.

What seems to work fine everywhere is this formats : VP8 and Vorbis in WebM ; H.264 and MP3 in MP4; H.264 and AAC in MP4. Specific informations can be found here :
