title: Facebook Open Graph Debugger response code 0
body: <p>I have problems with my domain and Facebook Open Graph Debugger. It <a href="https://developers.facebook.com/tools/debug/sharing/?q=eldoradoexperience.org%2Fchapter%2Fcosmos" rel="nofollow">returns</a> a Response Code 0 for this <a href="http://eldoradoexperience.org/chapter/cosmos" rel="nofollow">link</a> which is completely accesible.</p>
  
  <p>My HTML source code is valid, I tried hosting the same page in another domain and then Facebook Open Graph Debugger can read the content fine.</p>
  
  <p>Any ideas about this problem? I was using CloudFlare in this domain, but I disabled it 30 hours ago and the problem is still there.</p>
