I tried both with Firefox/Chrome on Ubuntu and they both play.

The first link is HTTP/1.1, the second uses HTTP/2 and is served via 
CloudFlare. Both webservers set the Content-Type to "video/mp4", which 
is what you want. This tells the browser what media type this is and how 
it should be handled. So far, so good.

The browser then needs to have an application associated with the 
content type in question in order to display whatever media the server 
is sending.

Now MP4 isn't always that straightforward, as the video could be encoded 
with a variety of different video codecs. It could be that the devices 
where this doesn't work can play MP4 in general, but not videos encoded 
with this particular codec. Which seems to be "H264 MPEG-4 AVC Part 10" 
and the included audio is "MPEG AAC Audio".

If it doesn't play on an iPad, then I would bet that this is a codec 
issue and you may have more luck converting the video into a different 
format with a codec that is natively supported on the version of iPad 
you're using:
