Background Video custom Code problem

Hello, I used Background video component that webflow provide.

However the quality is not good.

So I tried to add embed component.

  1. I made dropbox account and uploaded my video file.
    link (Dropbox - About_01_02.mp4 - Simplify your life)

  2. I changed link to “https://dl.dropboxusercontent.com/s/6vdn06iu3gm7bkx/About_01_02.mp4dl=0”.

  3. Added custom code like this

  1. I can see the video on webflow designer, but after publish when I checked the video on my domain adress, I can’t see the video.

I tried to fix this problem, but I really can’t find any solution.

Please help me thank you!
