    I think it is a mismatch for the IP address

    The following example shows how to reject connections from the IP

    $ sudo firewall-cmd --zone=public --add-rich-rule='rule family="ipv4" source address="" reject'

    Don’t know why learn additional language and command option set (like those of firewalld/ufw/shorewall) when iptables syntax is very structured, flexible and not that hard by itself.

    My needs are satisfied completely by ‘iptables-persistent‘ Ubuntu package and by iptables service in RHEL/CentOS.
