title: Facebook not recognizing my SSL certificate
body: <p>I have a site built in angularjs and working with prerender.io and with a SSL certificate from rapidssl and everything work fine...</p>
  
  <p>Except from Facebook that is not showing the right information for the page.</p>
  
  <p>When I open Facebook crawler</p>
  
  <p><code>Can't validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid.
  </code></p>
  
  <p>And is not recognizing the values og:url, og:type, og:title, og:image, og:description, fb:app_id</p>
  
  <p>It was working in the past, but it stop working I don't know why.</p>
  
  <p>I googled and I concatenated my ssl.crt and my intermidiate.crt but without result.</p>
