Thanks to everyone especially @SAMSAL. I got to know it is the firewall that was blocking the communications among the ports. I tried to add those ports to firewall but no much success. When i tried to reach NIFI GUI, i ran into this error:  java.net.NoRouteToHostException: No route to host (Host unreachable). So i disable the firewall & everything worked perfectly.   FIRST METHOD: NO SUCCESS firewall-cmd --zone=public --permanent --add-port 9991/tcp firewall-cmd --zone=public --permanent --add-port 2888/tcp firewall-cmd --zone=public --permanent --add-port 3888/tcp firewall-cmd --zone=public --permanent --add-port 2181/tcp firewall-cmd --reload   SECOND METHOD: SUCCESS systemctl stop firewalld ...
