EAP Domain Mode JMX Remoting Help

I am having a hard time connecting to JBOSS EAP 6.2 running in Domain Mode using the following URLs to connect to server-one and server-two (this is using an unmodified, default configuration from install).

service:jmx:remoting-jmx://localhost:4447
service:jmx:remoting-jmx://localhost:4597

I'm using the admin account I created during install. I can, however, connect to EAP running in Standalone Mode using the following URL without issue.

service:jmx:remoting-jmx://localhost:9999

At this point I'm not sure what else needs to be done to gain access to these systems. Any help is greatly appreciated.
