title: Registering achievements: Object Base Domain Not Allowed, even when domain IS allowed
body: <p>I have an Open Graph achievement at the following URL:</p>
  
  <p><a href="http://rinth.bucket1.s3.amazonaws.com/Achievements_LOCAL/Achievement1.html" rel="nofollow">http://rinth.bucket1.s3.amazonaws.com/Achievements_LOCAL/Achievement1.html</a></p>
  
  <p>When I attempt to register it, I get a response of: status code 400:  OAuth "Facebook Platform" "invalid_request" "(#3502) Object at achievement URL is not of type game.achievement"</p>
  
  <p>When I bring up the debug tool to have it validate the HTML:</p>
  
  <p><a href="http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Frinth.bucket1.s3.amazonaws.com%2FAchievements_LOCAL%2FAchievement1.html" rel="nofollow">http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Frinth.bucket1.s3.amazonaws.com%2FAchievements_LOCAL%2FAchievement1.html</a></p>
  
  <p>I get the following errors:</p>
  
  <p>Object Base Domain Not Allowed: Object at URL 'http://rinth.bucket1.s3.amazonaws.com/Achievements_LOCAL/Achievement1.html' of type 'game.achievement' is invalid because the domain 'rinth.bucket1.s3.amazonaws.com' is not allowed for the specified application id '217132388329112'.</p>
  
  <p>Missing Required Property: The og:url property is required, but not present.
  Missing Required Property: The og:type property is required, but not present.
  Missing Required Property: The og:title property is required, but not present.</p>
  
  <p>I verified that this domain IS allowed by our application.  Just in case, I also tried the entire process using a different domain (which resulted in the exact same error).</p>
  
  <p>The graph URL at the bottom of the debug tool prints the following:</p>
  
  <p>{
     "error": {
        "message": "An unknown error has occurred.",
        "type": "OAuthException"
     }
  }</p>
  
  <p>Any ideas on what I'm doing wrong?</p>
