title: Connection Failed to remote jupyter notebook
body: <p>I'm trying to connect to jupyter notebook running on my remote server.  The code below has been working fine for days to forward the jupyter notebook running on the port on my ubuntu server to my mac.  It stopped today.  Does anyone know what the issue might be?  Also does anyone know how I can just open the port on my ubuntu server so I wouldn't need the code below?  </p>
  
  <p>code:</p>
  
  <pre><code>ssh -L 8000:localhost:8888 username@111.111.11.122
  </code></pre>
  
  <p>Update:</p>
  
  <p>code:</p>
  
  <pre><code>jupyter notebook --no-browser --port=8889
  </code></pre>
