Issue Failed to restart firewalld.service when fail2ban.service exists

[nethubonline]

Server operating system version

AlmaLinux 9.5

Plesk version and microupdate number

18.0.65 #1

Hi all,

After I fresh install the Plesk with fail2ban and firewalld, I can't restart firewalld

# systemctl restart firewalld
Failed to restart firewalld.service: Transaction contains conflicting jobs 'restart' and 'stop' for fail2ban.service. Probably contradicting requirement dependencies configured.
See system logs and 'systemctl status firewalld.service' for details.

But I can restart firewalld after I stop fail2ban

# systemctl stop fail2ban
# systemctl restart firewalld
# systemctl start fail2ban

If I update /usr/lib/systemd/system/fail2ban.service as below, firewalld can be restarted successfully

PartOf=iptables.service firewalld.service ip6tables.service ipset.service nftables.service

to

PartOf=firewalld.service nftables.service

Not sure if this is a bug or if I'm the only one with this problem, please help.
