Root Cause: The DUAS hostname resolution is not working. No answer with the ping "hostname" command.

In this specific case, the server hostname was deleted from the /etc/hosts file and so resolution was not possible.
Resolution:
  1. Check the values.xml file and make sure the host name is pointing to the right host name or local IP address.
  2. Make sure the DNS is resolving to the hostname indicated in the values.xml file.
  3. Try to ping the hostname and verify that hostname resolution is possible.
Use netstat -a or nslookup commands to confirm host resolution.
  1. Check /etc/hosts file to avoid IP address conflict or a wrong definition for the host.
  2. Check that there is no clone of the Server hosting Dollar Universe on the network using the same IP address
