Youtube video not working in header now uploaded on a GoDaddy website
<p>I am a beginner at this coding thing and made a personal website/portfolio. Basically, the video header that once worked (works offline aka not uploaded to GitHub), no longer works.</p>

<p>Here it works: <a href="http://stephanie-heintzman.bitballoon.com/" rel="nofollow noreferrer">http://stephanie-heintzman.bitballoon.com/</a></p>

<p>Here it doesnt: <a href="http://stephanieheintzman.com/" rel="nofollow noreferrer">http://stephanieheintzman.com/</a></p>

<p>Can anyone please suggest why it doesn't work?</p>
