title: How to enable port 5000 on AWS ubuntu
body: <p>I have a flask app running on AWS Ubuntu server on port 5000 (flask runs default on port 5000). But when I try to access the server on that port, it never connects.</p>
  
  <p>I added a security group on AWS console as <code>Custom TCP</code> on port <code>5000</code> for any ip address <code>0.0.0.0/0</code>, but still I cannot access it.</p>
  
  <p>Do I have to restart the server? Or am I missing anything?</p>
  
  <p>Let me know any additional information to provide.</p>
