  /usr/local/lib/python3.5/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:318: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this.

  </code></pre>
  
  <p>I checked to see if Pip was recent:</p>
  
  <blockquote>
    <p>pip 9.0.1 from /usr/local/lib/python3.5/site-packages (python 3.5)</p>
  </blockquote>
  
  <p>And Python:</p>
  
  <blockquote>
    <p>Python 3.5.5</p>
  </blockquote>
  
  <p>OpenSSL:</p>
  
  <blockquote>
    <p>OpenSSL 1.0.2o  27 Mar 2018</p>
  </blockquote>
  
  <p>urllib is installed:</p>
  
  <blockquote>
    <p>Requirement already satisfied: urllib3[secure] in /usr/local/lib/python3.5/site-packages</p>
  </blockquote>
  
  <p>What am I missing that causes this TLS v1 error?</p>
  
  <p>I did upgrade Python from 3.5.1 to 3.5.5 thinking that would solve it, as it's from 2018.</p>
