title: Web app on VM server ERR_CONNECTION_REFUSED
body: <p>Edit: I am making this question more generic</p>
  
  <p>I am using Play! framework. I ran the dist command with no errors and unzip on a linux vm and I ran the ./appName file</p>
  
  <pre><code>$ ./appName
  Play server process ID is xxxx
  [info] play - database [default] connected at jdbc:postgresql://mydatabase:port/schema
  [info] play - Application started (Prod)
  [info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000
  </code></pre>
  
  <p>The webpage myservername:9000/  shows <code>ERR_CONNECTION_REFUSED.</code> 
  I tried different ports, using the IP address of the server. Also the logs don't show any errors</p>
