CHECK_NRPE: Error - Could Not Complete SSL Handshake

When I try to check the NRPE function using:
# /usr/local/nagios/libexec/check_nrpe -H localhost
, it returned the error:
CHECK_NRPE: Error - Could not complete SSL handshake

I have tried the steps mentioned in
https://support.nagios.com/kb/article/n ... e-615.html

The result returns for
# ls -la /etc/xinetd.d/nrpe
is
-rw-r--r-- 1 root root 486 Aug 4 14:41 /etc/xinetd.d/nrpe
so I went through the 'XINETD' section.
The line in the /etc/xinetd.d/nrpe in my case is
only_from = 127.0.0.1 localhost 10.10.110.24
whereas 10.10.110.24 is the IP address of the Nagios Core.

Afterwards, I followed the steps in 'SSL Not Compiled In:' section.
The message I got from
# /usr/local/nagios/libexec/check_nrpe -H localhost
now is
Connection refused by host

What is my next step to troubleshoot the issue?
