TA-Server

Telnet

For this step, we used “telnet agent-ip listening-port” to verify this issue.

  • The issue may be caused by a destination IP address that is unreachable.

    • The agent may have been moved to an external LAN.
    • The server may be unable to route to the agent.
  • The issue may be caused by FW blocking the IP address:port. To confirm the issue, contact the customer network administrator.
  • The issue maybe caused by the Tmlistem.exe process stopped on the agent.

    Next Steps

    • Reload the agent to verify whether this issue can be fixed.
    • If the tmlisten.exe process is still not running, contact Trend Micro Technical Support to fix this issue.

TA-Agent

SATA Agent

To verify the issue, we will use the command: telnet Server-IP/FQDN/Hostname Server-SSL-port.

  • This issue maybe caused by the destination IP address was unreachable.

    • The agent may have been moved to external LAN.
    • The agent may be unable route to the Server.
  • This issue may be caused by the FW blocked the OSCE/ApexOne-Server-IP:SSL-port traffic.

Next Step

  • Contact your customer network administrator to confirm it.
