Discord unable to embed videos larger than 2MB

I've got a web application that allows users to embed videos.
I'm currently facing an issue where videos that are roughly under 2MB embed fine, but videos >2mb don't embed at all
Anyone know what could be causing this?

The meta tags:

<title>Video</title>
<meta property="og:type" content="video" />
<meta name="description" content="Video Player" />
<meta name="og:video" content="<redacted url>/9T8K086M.mp4" />
<meta name="og:url" content="<redacted url>/9T8K086M.mp4" />
<meta name="og:video:secure_url" content="<redacted url>/9T8K086M.mp4" />
<meta name="og:image" content="https://<redacted url>/9T8K086M.png" />
