title: #LinkedIn LinkedIn's OpenGraph scraper not accepting SSL certificates released by Letsencrypt
body: <p>To the LinkedIn API support team</p>
  
  <p>I'm using free SSL certificates released by letsencrypt dot org, the new open certification authority.
  Linkedin's bot fails to scrape OpenGraph tags on my blog, because of an SSL issue on the client side (the certificate is unknown for the client, Linkedin scraper doesn't trust it), so I can't actually share my contents with proper OpenGraph parsing.
  What I see from the nginx logs is:
  SSL_do_handshake() failed (SSL: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown:SSL alert number 46) while SSL handshaking.
  Other opengraph-enabled social sites work as expected.</p>
  
  <p>Could you please take a look at this?</p>
  
  <p>Thank you!</p>
