On the remote machine can you run the following to see of it is listening on 5666
If that comes back succeeded, then from your nagios XI server run the following to see if your XI server can reach the remote host on 5666

Code: Select all
Connection to localhost 5666 port [tcp/nrpe] succeeded!
Can you run the following and try again
Also, can you post the results of the following command
