What happened?

The mp4 video on the page results in:

Failed to load resource: net::ERR_CONNECTION_FAILED

This reduces the "Best Practices" score :-(

What did you expect?

Either download the video properly or at the very least not mark this as a violation of best practices - it's a normal video.

Hi @lusayaa — I'd like to work on this if that's alright. Planning to first confirm whether the failed MP4 request is a genuine audit-logic issue or a host/CDN-side connectivity problem before proposing a fix.
