Agent installed?
Prove communication.
A structured RCA for managed endpoints that stop checking in with Endpoint Central or fail to receive expected management actions.
Validate local health
Confirm the agent service/process is present, running and not repeatedly crashing. Capture local timestamps and relevant agent logs.
Trace the path
Validate DNS, proxy configuration, outbound reachability, required ports and TLS/certificate inspection where applicable.
Confirm management state
Compare the endpoint's last contact with the server-side device record and a known-good endpoint on the same network.
Trace endpoint to console.
Endpoint baseline
Compare agent version, OS state, service status and recent reboot or configuration changes with a healthy endpoint.
Connectivity
Prove name resolution and the actual network path rather than assuming internet access means management connectivity works.
Management record
Correlate last-contact time, device identity and expected management action on the Endpoint Central side.
Do not reinstall the agent as the first response. Establish whether the failure is local agent health, DNS, proxy, network reachability, TLS/certificate handling, server availability or device identity. Remediate the demonstrated cause and confirm a fresh successful check-in.
