netdata agent does not visualise the chart

Good afternoon. I am new to netdata, so I may still be confused about the terminology.

on my production server, the netdata agent is already running and collecting data, visualisation is working, including correct display of mysql plugins, etc.

But now I need to have a chart created for freeradius.
I used the documentation for installing the plugin - FreeRADIUS | Netdata - and it doesn’t work (:

Here is what I have:

cat /etc/netdata/go.d.conf
modules:
  example: no
  prometheus: no
  k8s_state: no
  k8s_kubeproxy: no
  k8s_kubelet: no
  nginx: yes
  mysql: yes
  postgres: yes
  supervisord: yes
  freeradius: yes
  phpfpm: yes
  redis: yes
  openvpn: yes

Status work in freeradius:

server status {
        listen {
                #  ONLY Status-Server is allowed to this port.
                #  ALL other packets are ignored.
                type = status

                ipaddr = 127.0.0.1
                port = 18121
        }
....
        client admin {
                ipaddr = 127.0.0.1
                secret = adminsecret
        }
...
