title: Localtunnel is not setting up the requested subdomain from the command 'lt --port 4000 --subdomain xyz'
body: <p>I have been trying to set the subdomain in localtunnel, but it keeps throwing me different subdomains. </p>
  
  <p>Port number is 4000 and it's running.</p>
  
  <p>The command which I used : 
        <code>lt --port 4000 --subdomain xyz</code>  (I changed subdomain name for the security reason).</p>
  
  <p>Where am I doing wrong? </p>
