title: Omniauth Facebook Error - Faraday::Error::ConnectionFailed
body: <p>(FYI: I'm following the Twitter Omniauth from railscast #241. I used Twitter successfully, now going onto Facebook)</p>
  
  <p>As soon as I logged into Facebook using Omniauth, I get this error:</p>
  
  <pre><code>Faraday::Error::ConnectionFailed
  SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed
  </code></pre>
  
  <p>What does this mean?</p>
  
  <p>This is my code</p>
  
  <pre><code>Rails.application.config.middleware.use OmniAuth::Builder do
    provider :facebook, '&lt;key from fb&gt;', '&lt;another key from fb&gt;'
  end
  </code></pre>
  
  <p>There's actually nothing much in my code, all I have is in the sessionController that I want to use to_yaml to see what's inside the request.env</p>
  
  <pre><code>class SessionsController &lt; ApplicationController
      def create
          raise request.env["omniauth.auth"].to_yaml
      end
  end
  </code></pre>
  
  <p>How do I solve the Faraday error?</p>
