The only thing I see above that might be an issue is the 'Unknown' next to the MAC address. Could that be a factor?[root@ip-10-X-X-X ~]# nmap 10.X.X.X -p 5666

I looked through the kb article you provided the link to - I have not attempted to recomple nrpe with ssl explicitly allowed. I installed with the default. Is it worth trying that?
