title: RCurl errors when fetching ssl endpoint
body: <p>RCurl is giving me an <code>error:1411809D:SSL routines:SSL_CHECK_SERVERHELLO_TLSEXT:tls invalid ecpointformat list</code> when I try to connect via SSL to an https (not public, unfortunately) endpoint to fetch some JSON.</p>
  
  <p>I've put <code>ssl.verifypeer = FALSE</code>, and I don't know how to adjust the cipher list to avoid ECC suites.</p>
  
  <p>How do I fix this? It works fine in the browser.</p>
