Nagios Support Forum

Hello,
Good day!
We are monitoring hundreds of Web servers as services in Nagios XI. we are using Appchecker.cfg. We are getting a lot of error "Services Not Working - Error 127.0.0.1:65009" (there several ports). What can cause this issue? As some servers are using same CFG file and working.

Please advise.
Thanks,
Ann

Can you see 65009(and other ports) open on the PG1047 machine? Run netstat -na on PG1047 to check.

What is the command being used to run this check? Is it using a nrpe agent to run the check?
