Media Player on HTML

So I’ve spent the last few days trying to get the Media Player to play on HTML but I was unable to do so outside of the Editor.

Within the editor all is well and fine. I can play embedded media, streamed media and use the web browser both as Material for meshes or Textures for the UI.
Unfortunately, once I publish to HTML no media will play, neither locally nor uploaded to the web.

Here are the examples:

Project Files:

If you inspect the HTML on Firefox/Chrome it say this (Both locally or remotely run):

Error loading this URI: Could not load

I have also attempted to run this on UE4.20 preview 3, with no success as well.
Installing the Media Framework Plugin also crashed the HTML.

So is the Media Player even supported on HTML yet? OR am I just missing something?
