title: Rails - Curb SSLCA error? - Curl::Err::SSLCACertificateError
body: <p>When I update my Rails gems I find this errors (only in production, in development environment working good):</p>
  
  <pre><code>Curl::Err::SSLCACertificateError
  </code></pre>
  
  <p>Seems that is an SSL Certificate Authority Error, but why only in production is not working? And what can I do to resolve the problem?</p>
  
  <p>My curb gems is v.0.8.3 with rails 3.2.8
  (the mayor update was the rake, that now is v.10.0.2, but I don't know if this influence the good working of the curb gem). </p>
  
  <p>FYI, this is the code that raise the error: </p>
  
  <pre><code>    loginData = { :login =&gt; "myuser", :password =&gt; "mypass" }
      loginJson = ActiveSupport::JSON.encode(loginData)
  
      req = Curl::Easy.http_post("https://mysite.com", loginJson
      ) do |curl|
          curl.headers['Content-type'] = 'application/json'
      end
  </code></pre>
