Problem

The agent is not able to ping the server. Agent log shows an error similar to the following, pointing to a DNS problem:

javax.naming.CommunicationException: Failed to connect to server localhost:8085

Resolution

1. Update the DNS records to include the appropriate server name & IP used in the configuration file. If updating the DNS server is impossible
   Similar results can be achieved by updating the hosts file on the Bamboo server itself (local administrator rights on the server are needed).
   Common file location based on OS:

   OS	Location
   Linux	/etc/hosts
   Windows	C:\Windows\System32\drivers\etc\hosts

   
   Make sure the entry must contain an IP address and corresponding server name:  

   <IP of server>    <host name of server>
   192.168.1.123     atlassian.com

2. Restart the agent
