title: cURL error 35 - Unknown SSL protocol error in connection to api.rkd.reuters.com:443
body: <p>From development machine (mac) there is no problem connecting via cURL in PHP to this, but in Ubuntu, I get this error. I've tried on a local machine and on an Amazon AWS instance. I've googled and googled and keep coming up to brick walls. There's no firewall restrictions in place, its a complete mystery. php5-curl IS installed in ubuntu, I just don't have any ideas. I ran this command:</p>
  
  <pre><code>curl -v https://api.rkd.reuters.com/api/2006/05/01/TokenManagement_1.svc/Anonymous
  </code></pre>
  
  <p>and got this output, no clues whatsoever to a solution. OpenSSL is also installed.</p>
  
  <pre><code>* About to connect() to api.rkd.reuters.com port 443 (#0)

  <p>Any ideas welcomed on this</p>
