- Plesk Onyx for Linux
When Fail2Ban is enabled and has already banned some IP addresses, its rules in iptables can be removed when Plesk Firewall is disabled.
Plesk Bug #PPPM-9399 that is planned to be fixed in future product updates.
Until a fix is available, restart Fail2Ban as a workaround. For that:
- Log into the server via SSH.
- Restart Fail2Ban:
# service fail2ban restart
