If an agent fails to register with the Controller, a Performance Analyst should check the network/firewall rules to ensure that the agent can communicate with the Controller over the network. Additionally, it is crucial to verify the free license count to confirm that there are available licenses for the agent to register. Insufficient licenses or network communication barriers can prevent successful agent registration.
