Shinken docker SSL handshake issue - Remote host

Hi all,

I have Shinken inside docker container running on a host. Then I have remote hosts where I have NRPE installed. They are not on the same machine. Docker IP address is and then I installed the following packages on the remote host:
apt-get install openssl nagios-nrpe-server nagios-plugins nagios-plugins-basic nagios-plugins-standard
But when I run the check_nrpe command from inside the Shinken docker container, I get the SSL handshake error:

root@containerID:/usr/lib/nagios/plugins# ./check_nrpe -H
CHECK_NRPE: Error - Could not complete SSL handshake.

I changed the followings on my remote host is the allowed_hosts:
sudo echo ‘dont_blame_nrpe=1’ >> /etc/nagios/nrpe_local.cfg
Then rebooted the service: sudo service nagios-nrpe-server restart

Can someone please let me know what I did wrong?
