Lightbox URL video URL not supported

I am trying to recreate the video play button like on the wappler.io home page. I have tried to do everything the same way, but I am getting a URL not supported when the lightbox opens. What is odd is that I have one video that will play but when I use the current video it will not. Here is the link, the Font Awsome Icon launches the lightbox. The examples below are two different videos, both compressed the same way, and both approximately the same length.

this is the link that opens the lightbox with URL not supported:

Any ideas on what is causing this issue?
