I have the same problem, it is intermittent, after a few minutes it reloads.
sometimes it says error 502 BAD GATEWAY
Hi and welcome to the forum
Do you still have that problem? as far as it seems to me it started to work.

It would be faster if you upload the video file to YouTube (if you own the copyright) and then use it as background (via the corresponding code).
Then don’t use a proxy
It’s a matter of speed, once you have a video file in the browser cache, it goes fast,
but first-time visitors to your site won’t see the video quickly,
because this is website hosting and then some of the media extensions (mp3, mp4, etc.) are under bandwidth throttling (they download slower) so it takes longer for your video to appear.
When I wrote it, it worked
but right now 185.27.134.57 is down (and a few more IPs)
how long does it take to solve? I have more than 24 hours with the intermittent problem
It will be solved when the underlying problem is discovered. It could be 1 hour, or it could be more. There is no way to currently tell.
