Issue Fail2Ban doesn't works

[Zicane]

Hi, I have the same Fail2Ban setting I had before the plesk update. From the panel I can see it, but It does not ban any IP at the moment, but the jails and the settings are the same.
Someone can help me?

Check that service is started, make sure that there are no critical errors in fail2ban log: Plesk for Linux services logs and configuration files
Just usual troubleshooting as always.
