If your Application Agent is not reporting data to the Controller, checking the following items on the machine where the Agent is installed:
ssl-enabled
property value set to true?
/opt/appdynamics
folders and sub folders. If user "jboss" doesn’t have the permission to navigate to root-owned folders within AppDynamics, the Agent wouldn’t be able to write to log files that are required by the application.<AgentDir>/ver4.x.x.x/

These are excellent steps! Thanks,
The only thing I will add is that to check the Blue notifications icon next the the gear symbol. Most likely the issue is registered in the Notifications at the Vontroller interface.
example:
I commonly use chown -R user:group appdynamics
If your user is "jboss" chown -R jboss:jboss appdynamics
this gives the app agent user jboss complete ability to navigate the /opt/appdynamics forlder and all sub folders. If user "jboss" as an example does not have rights to navigate to root owned folders within appdynamics, then the agent would not be able to write to log files that is required by the application.
The above could be one of the main causes to permission denied.
