title: Can't open link from jupyter project
body: <p>I am new at using jupyter notebook. I build a dashboard using jupyter and dash, then it give me link to open my project</p>
  <pre><code>  Dash is running on http://127.0.0.1:8050/
  </code></pre>
  <p>But I can't open that link and the browser said &quot;This site cannot be reached 127.0.0.1 refusing to connect&quot;. I already change the 127.0.0.1 to my ip address, but still get the same error. When I open just my ip address it redirect me to localhost xampp. But, when I adding port after it, it gets the same error again.
  What configuration I can do to open that link ?</p>
  <p>Thank You :)</p>
