  <p>(<code>xxxx.xxxx.xxx.xx</code> Is an address that I use as proxy some times)</p>
  <p>I have Python version: 3.5.4</p>
  <p>and pip version: 9.0.1</p>
  <p>I have checked proxy settings with <code>netsh winhttp show proxy</code></p>
  <blockquote>
  <p>Current WinHTTP proxy settings:</p>
  <p>Direct access (no proxy server).</p>

  <p>I am not behind any corporate proxy
  My system proxy settings are</p>
  <blockquote>
  <p>Automatically detect settings -&gt; ON</p>
  </blockquote>
  <blockquote>
  <p>Use setup script -&gt; OFF</p>
  </blockquote>
  <blockquote>
  <p>Use a proxy server -&gt; OFF</p>

  <p>Also tried <code>ping pypi.python.org</code></p>

  </blockquote>
  <p>So, I have access to the internet</p>
  <p>Also i removed temp files, tried <code>python -m pip --proxy=&quot;&quot; install django==1.8.11</code>, searched the registry for data or value <code>xxxx.xxxx.xxx.xx</code>, same result...</p>
  <p>If anyone knows where is that <code>xxxx.xxxx.xxx.xx</code> configured so I can remove it, don't know what else to do.</p>
