title: App running on port, however localhost:5000 there is nothing there
body: <p>Randomly whenever I run an applications (e.g. npm start) and it'll say</p>
  <blockquote>
  <p>Server running on port 5000</p>
  </blockquote>
  <p>However when I try to access this using</p>
  <pre><code>http://localhost:5000
  </code></pre>
  <p>My browser gives a generic, this page can't be reached.</p>
  <p>This only happens every now and then however when it does, it applies to any app I try them on. I've found restarting my machine fixes the problem however this is not ideal.
  Does anyone know why this might be and a long term fix?</p>
