I am using CyberPanel 2.3 where CSF is automatically disabled. I am unable to enable it. Also, I can’t start the firewall. I run systemctl unmask firewalld and now firewall is Not Found. If I go to /configservercsf/ it’s showing

Not Found

The requested resource was not found on this server.

How can I able to install CSF? Or how can I able to start a basic firewall?

after unmask did you restart the firewalld as well or not?

No I didn’t. Should I?
