Is your controller able to do DNS queries ?
Need to add the following :
ip domain lookup
ip domain-name <controller_dns_name.your_domain_name>
ip name-server <DNS Server IP Address>
Note: In order for this to take effect the controller will need to be rebooted
Also need to make sure that the controller is able to talk to : aruba.brightcloud.com using 443 , that is how the controller gets all its Web Content information updates
Do you have PEF license ?
