It sounds like you've got NRPE up on your AWS system, so I think you
might need to take a closer look at your security groups to make sure
it is allowing the NRPE port in from the source you're checking from.
You could always check with a check_nrpe from another host in the same
VPC if you want to make sure its not NRPE configuration-related.
