body: <p>This is the first time I am trying to set up docker (version 17.09.0-ce). I have followed the all instructions from official site and this run ok on my machine (Windows 10 x64). When I type <code>docker --version</code> on console returns <code>Docker version 17.09.0-ce, build afdb6d4</code>. But i am trying execute <code>docker run -t hello-world</code> and this is the answer:</p>
  
  <pre><code>Unable to find image 'hello-world:latest' locally
  docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
  See 'docker run --help'.
  </code></pre>
