trend micro security agent offline but shows green connection

Sudo svcs -l svc:/application/ds_agent:default Look for the service named ds_agent, such as: On Solaris, open a terminal and enter the command for a process listing. Look for the service named ds_agent or ds-agent, such as: On Linux, open a terminal and enter the command for a process listing. On Windows, open the Microsoft Windows Services Console (services.msc) or Task Manager.On the computer with the agent, verify that the Trend Micro Deep Security Agent service is running. To troubleshoot the error, verify that the agent is running, and then that it can communicate with the manager. If you are using manager-initiated or bi-directional communication, and are having communication issues, we strongly recommend that you change to agent-initiated activation (see Activate and protect agents using agent-initiated activation and communication).

On AWS EC2, ICMP traffic is required, but is blocked.Deep Security rule update is not yet complete, temporarily interrupting connectivity.The agent's or manager's system time is incorrect (required by SSL/TLS connections).Certificates for mutual authentication in the SSL or TLS connection have become invalid or revoked (see Replace the Deep Security Manager TLS certificate).The manager, the agent, or both are under very high system resource load.DNS was down, or could not resolve the manager's hostname.Amazon WorkSpace computer is being powered off, and the heartbeat interval is fast, for example, one minute in this case, wait until the WorkSpace is fully powered off, and at that point, the status should change from 'Offline' to 'VM Stopped'.Guest Wi-Fi, for example, often restricts open ports, and has NAT when traffic goes across the Internet. This can occur if roaming endpoints (such as a laptop) cannot connect to the manager at their current location. Computer has left the context of the private network.Bi-directional communication is enabled, but only one direction is allowed or reliable (see Configure communication directionality).See Blocked port for troubleshooting tips. Outbound (ephemeral) ports were blocked accidentally.Firewall, IPS rules, or security groups block the heartbeat port number.In the policy editor, go to Settings > General > Number of Heartbeats that can be missed before an alert is raised and change the setting to 'Unlimited'. If you are using Deep Security to protect computers that sometimes get shut down, make sure the policy assigned to those computers does not raise an alert when there is a missed heartbeat. The agent is installed on a workstation or other computer that has been shut down.(See Configure the heartbeat.) The status change can also appear in alerts and events. A computer status of 'Offline' or 'Managed (Offline)' means that the Deep Security Manager hasn't communicated with the Deep Security Agent's instance for some time and has exceeded the missed heartbeat threshold.
