title: Facebook API OAuthException: “An unexpected error has occurred. Please retry your request later” when trying to retrieve a Page-specific access token
body: <p>I want my app to be able to post status updates to a specific Page. I've got an application set up and retrieved its app ID, and I'm following the the “Page Login” section at the bottom of the Facebook authentication documentation <a href="http://developers.facebook.com/docs/authentication/" rel="noreferrer">here</a>.</p>
  
  <p>The first stage (user granting the app the <code>manage_page</code> permission) seems to work perfectly. I get redirected to a URL like this:</p>
  
  <p><code>http://myapp.com/#access_token=ACCESS_TOKEN&amp;expires_in=6483</code></p>
  
  <p>The docs then say you should access the following:</p>
  
  <p><code>https://graph.facebook.com/me/accounts?access_token=TOKEN_FROM_ABOVE</code></p>
  
  <p>replacing <code>TOKEN_FROM_ABOVE</code> with the one returned by the previous request, and this should return “a list of all the Pages the user administers including Page specific access token for each Page”.</p>
  
  <p>However, it doesn't. All I get is the following JSON response:</p>
  
  <pre class="lang-js prettyprint-override"><code>{
      "error": {
          "message": "An unexpected error has occurred. Please retry your request later.",
          "type": "OAuthException"
      }
  }
  </code></pre>
  
  <p>What am I doing wrong? Could I have set something up incorrectly when creating the application? The error message is less than helpful, so any assistance would be much appreciated.</p>
