Youtube “Blocked a frame with origin ”http://www.youtube.com“ from accessing a frame with origin” even if the same protocol is used

问题

When embedding a Youtube playlist I am getting this error:

Blocked a frame with origin "http://www.youtube.com" from accessing a frame with origin "http://www.mydomain.com". Protocols, domains, and ports must match.

I am not mixing HTTP with HTTPS anywhere, so I don't know why I am getting this error in the first place.

I have noticed that recently the Youtube embedded playlist is not displaying the embed image of the first video and just displaying a black screen with a 'Play All' button, and I am wondering if this is being caused by the above error.

Apparently it seems that the error given by chrome is a bug. In order to solve the black screen with 'Play All' button issue I used the Javascript API (instead of the iframe), like this:

<!DOCTYPE html>
<html>
  <body>
    <div id="player"></div>
    <script>
      var tag = document.createElement('script');
      tag.src = "https://www.youtube.com/iframe_api";
      var firstScriptTag = document.getElementsByTagName('script')[0];
      firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
      var player;
      function onYouTubeIframeAPIReady() {
        player = new YT.Player('player', {
          height: '390',
          width: '640',
          videoId: '',
          events: {
            'onReady': onPlayerReady 
          }
        });
      }
      function onPlayerReady(event) {
        player.cuePlaylist({'listType':'playlist','list':'PLE2714DC8F2BA092D'});
      }
    </script>
  </body>
</html>

Thanks to @jlmcdonald for the answer, as indicated here: Youtube embedded playlist diplays playall button instead of the first video

this issue is quite apparent to the Youtube service, basically Youtube can be only accessed through https, http is not allowed now, just change your 'http' to "https"...that's the solution
