title: Jetty: HTTP ERROR: 503/ Service Unavailable after change the server ip address WHEN NO INTERNET CONNECTION
body: <p>I did install Opennms in a VM Ubuntu on PROXMOX. Everything went well until I did change the interface IP address because the VM must work in a LAN without Internet access. Since then the opennms start correctly but the browser give me the error:</p>
  
  <p>Jetty: HTTP ERROR: 503</p>
  
  <p>Problem accessing /opennms/. Reason:</p>
  
  <p>Service Unavailable</p>
  
  <p>The problem seems to be related with the connection to Internet at the starting of opennms. When I start opens without Internet connection the server do to start correctly.</p>
