title: When using create-react-app why does the development server keep disconnecting?
body: <p>It happens arbitrarily, like once every 3 or 4 refreshes, the server just disconnects with this message in the console:</p>
  <pre><code>The development server has disconnected.
  Refresh the page if necessary.
  </code></pre>
  <p>I looked at one of the other <a href="https://stackoverflow.com/questions/43274925/development-server-of-create-react-app-does-not-auto-refresh">SO posts</a> and my problem seems different because that's about the webpack watcher not connecting, to begin with, in my case it works but disconnects very often. I haven't even ejected the app so not sure why this can be.</p>
