Problem
Our KServer Agent is showing offline in the VSA, and our Kaseya Server is up and running. What could be the issue here?
Possible Cause
You have this agent using something else other than localhost for the Agent > Check-in Control values (Primary KServer and Secondary KServer).
Resolution
It's recommended to have the Primary KServer and Secondary KServer set to use localhost, on port 5721 (default port for agents to check-in), or custom port if applicable.
Note: If the above is set to use localhost, yet this agent keeps showing offline in the UI, please gather agent logs and reach out to Kaseya Support for further assistance.
