title: Can't update chromedriver and seleniumrelease
body: <p>I try to work with protractor. So I followed a small tutorial and the first thing I did:</p>
  
  <pre><code>npm install -g protractor
  </code></pre>
  
  <p>This will install two command line tools, protractor and webdriver-manager.
  But now I have to update my webdriver-manager:</p>
  
  <pre><code>webdriver-manager update
  </code></pre>
  
  <p>So my cmd tries to connect with <a href="https://chromedriver.storage.googleapis.com/2.14/chromedriver_win32.zip">https://chromedriver.storage.googleapis.com/2.14/chromedriver_win32.zip</a> and <a href="https://selenium-release.storage.googleapis.com/2.45/selenium-server-standalone-2.45.0.jar">https://selenium-release.storage.googleapis.com/2.45/selenium-server-standalone-2.45.0.jar</a>.
  But it will give this error:</p>
  
  <pre><code>C:\Program Files (x86)\Jenkins\workspace\testnew&gt;webdriver-manager update
  Updating selenium standalone
  downloading https://selenium-release.storage.googleapis.com/2.45/selenium-server
  -standalone-2.45.0.jar...
  Updating chromedriver
  downloading https://chromedriver.storage.googleapis.com/2.14/chromedriver_win32.
  zip...
  Error: Got error Error: getaddrinfo EAI_AGAIN from https://selenium-release.stor
  age.googleapis.com/2.45/selenium-server-standalone-2.45.0.jar
  Error: Got error Error: getaddrinfo EAI_AGAIN from https://chromedriver.storage.
  googleapis.com/2.14/chromedriver_win32.zip
  </code></pre>
  
  <p>Sometimes it is the EAI_AGAIN error and sometimes ENOTFOUND.
  But what I don't understand is that I can download the zip and the jar manually in my browser. When I surf to the URL it all works fine. But not in the cmd. Can someone help me?
  PS: pinging isn't possible to the url's</p>
  
  <p>Update: after proxy settings I get this error: </p>
  
  <pre><code>Error: Got error Error: tunneling socket could not be established, cause=socket
  hang up from https://chromedriver.storage.googleapis.com/2.14/chromedriver_win32
  .zip
  </code></pre>
