connect to address <<myIP>> and port 22: No route to host about ansible-nagios

@sadsfae Just to update when I stop firewalld I did not get this error. With rich rule I have allowed all port for my network but still getting this error.

rule family="ipv4" source address="192.168.128.0/17" accept
 rule family="ipv4" source address="192.168.128.0/17" service name="ssh" accept
 rule family="ipv4" source address="192.168.128.0/17" port port="5666" protocol="tcp" accept

hey @ranjeetranjan if it works with firewalld stopped it's most likely your firewalld ruleset. Red Hat seems to think you also need UDP/5666 open as well (though on my system only TCP/5666 is needed).

Try:

firewall-cmd --zone=public --add-port=5666/udp --permanent
firewall-cmd --zone=public --add-port=5666/tcp --permanent
firewall-cmd --zone=public --add-port=22/tcp --permanent
firewall-cmd --reload

Closing this out, please try the above suggestions. If that doesn't work you should try the Ansible ping command which will detect connectivity between Ansible and your hosts.

ansible -u root -i hosts all -m ping
