body: <p>I am following the <a href="https://www.tensorflow.org/versions/r0.9/get_started/os_setup.html#docker-installation" rel="nofollow noreferrer">tutorial of TensorFlow</a> and setting up the docker image on my windows 7 machine. </p>
  
  <p>I receive this message <code>Error checking TLS connection: Host is not running</code> message my Windows Command prompt tries to reach the docker images executed on VirtualBox.</p>
  
  <h2>The steps</h2>
  
  <ul>
  <li>I have <a href="https://docs.docker.com/engine/installation/" rel="nofollow noreferrer">Docker 1.8 installed</a> (latest version as we speak)</li>
  </ul>

  <ul>
  <li>I have VirtualBox v5.0.20 installed (latest)</li>
  <li>Docker is running correctly</li>
  </ul>

  </ul>
  
  <h2>Under the windows command prompt</h2>
  
  <ul>
  <li>I run <code>c:\ml\tensorflow&gt;FOR /f "tokens=*" %i IN ('docker-machine env --shell cmd vdocker') DO %i</code> and get the following error message <code>Error checking TLS connection: Host is not running</code></li>
  <li>I run <code>docker-machine ls</code> command and I get timeouts</li>
  </ul>
