Fail2Ban - Failed to access socket path

Hi together,
I have installed "fail2ban 0.11.2-5" and "freeswitch-mod-fail2ban 1.10.7-1" on OpenWrt 21.02.0. When I run
"/etc/init.d/fail2ban start"
I can see

/etc/init.d/fail2ban status
running.

But "fail2ban-client status" delivers
2022-03-15 10:14:22,926 fail2ban [640]: ERROR Failed to access socket path: /var/run/fail2ban/fail2ban.sock. Is fail2ban running?

The directory "/var/run/fail2ban/" exists but not the socket file "fail2ban.sock". What is wrong here?

Greetings
Diani
