Node events.js:167 throw er; // Unhandled 'error' event : <p>I'm trying to use JSON Server in a React App. However, I keep getting the following error. </p>

<pre><code>events.js:167
  throw er; // Unhandled 'error' event
  ^
Emitted 'error' event at:
at GetAddrInfoReqWrap.doListen [as callback] (net.js:1498:12)
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:50:17)
</code></pre>

<p>I've upgraded npm and node to the latest versions.
 I've killed all processes with killall node and sudo killall -9 node</p>

<p>Any ideas what may be causing the issue? </p>
