No Fail2Ban GUI in NethServer 7.3

NethServer Version: 7.3.1611
Module: fail2ban

Just configureed a new NethServer 7.3, and installed the Fail2Ban module, but somehow I can not find or see the Fail2BAN GUI or Service in the Dashboard. Don’t quite understand why, I successfully install Fail2ban in other systems before…

Appreciate any help to diagnose the problem.
