title: Facebook Object Debugger - Could not resolve the hostname into a valid IP address
body: <p>There is a problem with how Facebook scrapes my page for meta data.</p>
  
  <p>When I use the Facebook object debugger I get the following error:
  <img src="https://i.stack.imgur.com/2pr0n.png" alt="enter image description here"></p>
  
  <p>I am quite sure this has something to do with how my DNS records are defined. It seems the scraper can't even reach my site. As the error states, it can't turn the host name to a valid IP.</p>
  
  <p>When I press the link down the page "See exactly what out scra...", I get "Document returned no data".</p>
  
  <p>I am trying to figure it for about a month now and getting VERY VERY frustrated.
  Can someone shed some light on the subject ? </p>
