port 12489 Connection refused issue
Posted: Sun Aug 01, 2021 10:05 pm
I'm using NCPA to monitor a Windows machine with NRDP (passive check) and quite sure there's no port blocking issue as Windows firewall is now off.
The strange thing is "Memory Usage" can be monitored successfully, but all the others namely "CPU Load" and "Uptime" always show "connect to address x.x.x.x and port 12489: Connection refused".
All service configurations are identical except "check command" of course. I wonder if port 12489 really can't be reached then why "Memory Usage" is not affected?
