    Hi Hendra,
    this error can be cause by not having port 7182 opened on your CM server
    machine. Make sure that your firewall is not blocking TCP port 7182; you
    can try to telnet from the agent machine, i.e. telnet 192.168.75.128
    7182<http://192.168.75.128:7182/>
    .
    thanks,
    emanuel
