Error: Unable to resolve instance hostname
The error message "Unable to Resolve Instance Hostname" may occur as a result of activating the Agent from Deep Security Manager when you are not using agent-initiated activation.
We recommend that you always use Agent-Initiated Activation.To learn how to configure policy rules for agent-initiated communication and deploy agents using deployment scripts, see Activate and protect agents using agent-initiated activation and communication.
