title: ipython notebook kernel runs, but no connection
body: <p>My company makes me rotate my laptop each year.</p>
  
  <p>I am trying to re-install ipython with notebook (it worked just fine like this before).</p>
  
  <p>According to the command prompt, everything is hunky dory.</p>
  
  <p>[NotebookApp] The IPython Notebook is running at: //127.0.0.1:8888
  [NotebookApp] Use Control-C to stop this server and shut down all kernels.</p>
  
  <p>But, Chrome can't connect to //127.0.0.1:8888/</p>
  
  <p>I have a suspicion that it is a versioning problem with tornado, but was wondering if anybody else had faced similar issues?</p>
