Code:
firewall-cmd --get-active-zones
shows plesk and
Code:
firewall-cmd --zone=public --list-ports
shows 3579/tcp
The active zone is different right so I added rule in currently active zone
Code:
firewall-cmd --permanent --zone=plesk --add-port=3579/tcp
which solves the issue.
Thank. I'm new to linux environment so still learning
