title: invalid_client in google oauth2
body: <p>I try to make a web page for youtube video upload, therefore I try to get the client id from google api console, and in the api console it shows something like this:</p>
  
  <pre><code>Client ID: 533832195920.apps.googleusercontent.com
  Redirect URIs: http://bobyouku.ap01.aws.af.cm/testyoutube.php
  https://developers.google.com/oauthplayground
  </code></pre>
  
  <p>However when I try to test my account using the following URL:</p>
  
  <p><a href="https://accounts.google.com/o/oauth2/auth?client_id=533832195920.apps.googleusercontent.com&amp;redirect_uri=http%3A%2F%2Fbobyouku.ap01.aws.af.cm%2Ftestyoutube.php&amp;scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube&amp;response_type=code&amp;access_type=offline" rel="noreferrer">https://accounts.google.com/o/oauth2/auth?client_id=533832195920.apps.googleusercontent.com&amp;redirect_uri=http%3A%2F%2Fbobyouku.ap01.aws.af.cm%2Ftestyoutube.php&amp;scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube&amp;response_type=code&amp;access_type=offline</a></p>
  
  <p>It gives out the result of invalid_client. Even when I try it on oauth2 playground, same fail occurs</p>
  
  <p>So anyone knows what's happen?</p>
