If fail2ban is totally broken and if you didn’t have any filter or jail left in `/etc/fail2ban/jail.d` and `/etc/fail2ban/filter.d`, you can try reinstalling fail2ban. You will likely need to manually add files from [fail2ban repo](https://github.com/fail2ban/fail2ban/tree/master/config) and to recreate jails for your apps.
