title: cast_sender.js error: Failed to load resource: net::ERR_FAILED in Chrome
body: <p>I recently started receiving the following console errors, without any code changes taking place.</p>
  
  <p>I did not install any extensions recently.</p>

  <p>I have several YouTube player embeds on the page that are triggering this error, but they are simple:</p>
  
  <pre><code>&lt;iframe width="100%" height="100%" src="http://www.youtube.com/embed/OUR_YOUTUBE_ID?showinfo=0&amp;amp;wmode=transparent" frameborder="0" allowfullscreen=""&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>Has anybody else experienced this?</p>
