Oops  you've accidently started your controller with root user instead of your app service user (ie appd, appdynamics, etc...) ?


1. First stop controller (as root) 


2. As root, change permissions back to original user and group


chown -R <original user>:<original group> <controller home>


Ie: chown -R appd:appd /opt/appdynamics/controller


3. Start controller with your original user.


That's it.
