title: Getting oembed using YoutubeURL returns 403 Forbidden
body: <p>For A few days, I have suddenly become receiving the 403 Forbidden response from <code>https://www.youtube.com/oembed?url={youtubeURl}</code>.</p>
  <p>I have checked documents for Youtube API but I can't find that it has restrictions for getting oembed and has authorization too. I can only see a restriction for Youtube Data API.</p>
  <p>Why do I get the 403 Forbidden response from this API...?</p>
  <p>Sample sending request:</p>
