Why GoldenGate Monitor Agent 12.1.3 -> ogg_agent.log shows the following errors:
[2014-12-04T15:27:27.277+00:00] [JAGENT] [NOTIFICATION] [] [com.goldengate.monitor.jagent.config.impl.CmDelegateImpl] [tid: agentRegistration] [ecid: 0000KcLhPKH8DwT6yBmZMG1KW6tu000004,0] Closing client connection after registration == ClientConnectionImpl(com.goldengate.monitor.jagent.client.MonitorJmxConnectionInfo@7626fb7a)

[2014-12-04T15:27:27.278+00:00] [JAGENT] [ERROR] [OGGMON-20283] [com.goldengate.monitor.jagent.jmx.MBeansContainerImpl] [tid: agentRegistration] [ecid: 0000KcLhPKH8DwT6yBmZMG1KW6tu000004,0] [[ JAgent is unable to establish a connection to Monitor Server. Monitor Server is probably down. Retry again in 10 seconds. JAgent connection info: Jagent Host=<FULLY QUALIFIED HOSTNAME>, Jagent JMX Port=<port>, Jagent Config Dir=<path>/agent2/cfg, Monitor Host=<HOSTNAME>, Monitor Port=<port>]]
and targets are not getting registered in Oracle Goldengate(OGG) Monitor Server 12.1.3?

Another variation of this error is that the ogg_agent.log show no error.  But the monitor.log show a timeout connecting back to the agent:
