title: SSL Certificate error on Facebook Android App Only
body: <p>I'm using Gandi SSL certificate on my subdomain and it's working just fine except when website is accessed through Facebook Android app where I get a security error.</p>
  
  <p>I've doubled checked with <a href="https://www.sslshopper.com/ssl-checker.html#hostname=https://tickets.shotguntheapp.com/events/5569" rel="nofollow noreferrer">SSLShoper</a> and <a href="https://www.ssllabs.com/ssltest/analyze.html?d=tickets.shotguntheapp.com&amp;latest" rel="nofollow noreferrer">QUALYS SSL LABS</a>, with no issue with the chain reported.</p>
  
  <p>Website URL is <code>https://tickets.shotguntheapp.com/events/5569</code> and it can be accessed through Facebook by clicking "Tickets available" <a href="https://www.facebook.com/events/884560168242877/permalink/889478237751070/" rel="nofollow noreferrer">here</a></p>
  
  <p>Any clue where the issue could come from?</p>

  <ol>
  <li>First issue was a missing certificate in the chain as Anand
  explained it very well</li>
  <li>Second issue was in my Heroku <code>certs:update</code> command. If you run <code>heroku certs</code>, you might see two certificates, of type SNI and Endpoint. <strong>Both have to be updated!</strong></li>
