java.net.ConnectException: Connection refused

Problem:
This is one of the Common Exceptions which we come across daily in our lives. I encountered this issue when trying to publish few content instances of a particular type in CMS.

Exception i encountered was:

Solution:
The error was because, the CMS content was trying to invoke vda-01 server where as it had to invoke vda-02. Tried different possibilities with testing like making vda-01 down and running the code, which went fine and then made vda-02 down which triggered the error again. Since the vda servers where load balanced we had to go with single node server test and found the fault with vda-01 server. Notified the same to the network team eventually they rectified and resolved it :).
