Embedded code snippet content not showing on live website

Hi! I recently started building my first Squarespace website and it's been great! 

After publishing my website to my business domain, I encountered a problem. The videos I've embedded using the following code snippet do not appear on the live website meanwhile they seem to work perfectly in the editor

<video style="width: 100%"
  loop autoplay playsinline muted
  src="https://beige-bellflower-bw9x.squarespace.com/s/Website_Studio_vid_small.mp4">
    <source type="https://beige-bellflower-bw9x.squarespace.com/s/Website_Studio_vid_small.mp4">
</video>

Any tips on how to fix it? The picture I've attached is how it looks in the editor (multiple instances of this throughout the website)

Thank you so much for your attention and participation. (viewer code for the website is "hej")

Update:

In the inspector tool, it says

"Failed to load resource: the server responded with a status of 403 ()"

In all instances of the embedded videos
