title: Can't let firewall pass port 8065 at Oracle Cloud
body: <p>I'm setting up the service at Oracle Free Tier service; the service is up and running on local interfaces, but I can't reach it from outside (via public IP) on port 8065.</p>
  
  <p>No firewall rules on Ubuntu machine, Oracle firewall is configured and says "TCP traffic for ports: 8065". Exact same (build-in) rule works just fine.</p>
  
  <p>Oracle's Ubuntu default image, Linux's firewall seems to be disabled:</p>
  
  <pre><code>$ sudo ufw status
  Status: inactive
  </code></pre>
  
  <p>I'm getting "Connection refused" (TCP level) from outside, when trying to connect.</p>
  
  <p>Any help would be much appreciated.</p>
