title: Network timeout..cannot pull images
body: <p>My current operating system is Windows 10 and 
  I have installed Virtual Box and then added an Ubuntu VM on top of that. I installed the docker-engine on Ubuntu and I added the insecure-registry.
  But when I am trying to pull the images..it always says "Network timed out error". I have tried most of the suggestions from Google, but to no success.
  I cannot even pull images from public DockerHub like docker pull hello-world</p>
  
  <p>Please do help me .</p>
  
  <p>I am doing the commands in the following order</p>
  
  <pre><code>sudo docker pull hello-world
  </code></pre>
