I have uploaded three videos on my youtube channel, however, when I'm trying to put those three videos on my HTML website, among those videos one gets played, and the other two videos show the thumbnail but when I try to play it shows that the video is unavailable. I've attached the embedded code for that video.
<iframe width="100%" height="228" src="https://www.youtube.com/embed/U5jhsfVzcAk" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
It would be great if someone can suggest something on this!
