Resolved IP Address Banning, cannot turn on

[PeopleInside]

Server operating system version

20.04.4 LTS

Plesk version and microupdate number

18.0.44

Today I connected to Plesk and in the main home screen I discover IP Banning was off.
I clicked on the change link than checked the box Enable intrusion detection and saved.
A green message show:

Information: The settings were saved. but the check box still be unchecked and in the home screen still see IP Banning off.

How can I resolve?
Thanks.

Logs are empty. Sorry but this forum software is giving issue with all browsers
I tried also to unistall and install again fail2ban but nothing.

Try to start/stop/restart fail2ban in CLI according to https://support.plesk.com/hc/en-us/articles/213403509#f2b and check logs again.

The issue with posting on the forum will be fixed soon.

I started fail2ban with:

# service fail2ban start

and see in /var/log/syslog:

There is a way to get an email alert if for some reason Fail2Ban stop to work?

You can configure and use Plesk Watchdog component: Watchdog (System Monitoring) Component

I can't use as I'm on Ubuntu 20LTS where there is no watchdog

Wrote your own watchdog script in this case
