YouTube API onPlayerReady not firing

Question

I created a new page especially to test the API. When copy pasting their example with

<div id="player"></div>

and

 var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      height: '390',
      width: '640',
      videoId: 'M7lc1UVf-VE',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }

Everything works.

Now when I remove the <div id="player"></div> and instead replace it with

 <iframe id="player" type="text/html" width="640" height="390" src="http://www.youtube.com/embed/GuVq-TZ7AJM?enablejsapi=1" frameborder="0"></iframe>

It no longer works. It never goes in the onPlayerReady or onPlayerStateChange. The weird thing is it was working last night and today it isn't. I have attached my full code in case it may help.

<!DOCTYPE html>
<html>
  <body>
    <!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
    <iframe id="player" type="text/html" width="640" height="390" src="http://www.youtube.com/embed/GuVq-TZ7AJM?enablejsapi=1" frameborder="0"></iframe>


    <script>
      // 2. This code loads the IFrame Player API code asynchronously.
      var tag = document.createElement('script');

      tag.src = "https://www.youtube.com/iframe_api";
      var firstScriptTag = document.getElementsByTagName('script')[0];
      firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

      // 3. This function creates an <iframe> (and YouTube player)
      //    after the API code downloads.
      var player;
      function onYouTubeIframeAPIReady() {

        player = new YT.Player('player', {
          events: {
            'onReady': onPlayerReady,
            'onStateChange': onPlayerStateChange
          }
        });
      }

      // 4. The API will call this function when the video player is ready.
      function onPlayerReady(event) {
        alert('test');
        event.target.playVideo();
      }

      // 5. The API calls this function when the player's state changes.
      //    The function indicates that when playing a video (state=1),
      //    the player should play for six seconds and then stop.
      var done = false;
      function onPlayerStateChange(event) {
        if (event.data == YT.PlayerState.PLAYING && !done) {
          setTimeout(stopVideo, 6000);
          done = true;
        }
      }
      function stopVideo() {
        player.stopVideo();
      }
    </script>
  </body>
</html>

I recently had this issue and none of the answers worked for me. My problem was that I had created multiple YT.Player:s for the same iframe, and apparently only the first YT.Player will actually work while the others just fail silently. They don't fire any events and they lack all the playVideo(), pauseVideo() etc methods. — powerbuoy

Per issue 5670:

A quick fix is to add in the origin=http://www.example.com (replace with your servers full domain; make sure you use http:// or https:// as appropriate for your site) to the src= attribute of the player's iframe element. Please make sure that the origin= attribute's value exactly matches the host domain and URL scheme. E.g.
<iframe
  type="text/html"
  width="640"
  height="480"
  src="https://www.youtube.com/embed/VIDEO_ID?enablejsapi=1&origin=https://www.example.com"
  frameborder="0">
</iframe>
