title: Facebook Object Debugger: Curl Error : SSL_PEER_CERTIFICATE SSL: no alternative certificate subject name
body: <p>I am unable to test the open graph tags on a site using the Facebook object debugger (lint tool) (<a href="https://developers.facebook.com/tools/debug/og/object/" rel="noreferrer">https://developers.facebook.com/tools/debug/og/object/</a>). The errors returned are:</p>
  
  <pre><code>Object at URL 'https://www.musicharvest.org/' of type 'website' is invalid because a required property 'og:title' of type 'string' was not provided.
  
  Curl Error : SSL_PEER_CERTIFICATE SSL: no alternative certificate subject name matches target host name 'www.musicharvest.org'
  </code></pre>
  
  <p>and the result is that no open graph tags are interpreted.</p>
  
  <p>The site exists and the SSL certificate contains both www.musicharvest.org and musicharvest.org.</p>
  
  <p>Does anybody have an idea as to what the problem might be here?</p>
