AlarmEventViewer ComponentSample: Failed to connect to event server

I tried to run the AlarmEventViewer from MIPSDK ComponentSamples but

the follow error occurred.

According to my trace,

the error was trigger in the following statement of the method in MainForm.cs:

private void LoadClientAlarm()

{

.

.

.

IAlarmClient alarmClient = \_alarmClientManager.GetAlarmClient(EnvironmentManager.Instance.MasterSite.ServerId);

.

.

.

}

The IP of the MasterSite.ServerId is the same as my event server IP,

192.168.10.202.

Yet I failed to figure out why it trying to connect to 192.168.20.210.

Thanks and regards,
