I don’t understand why my fail2ban don’t work.

I create a custom jail for my web app :

[apache-app]
enabled = true
filter = apache-app
port = http,https
logpath = /var/log/myapp.log
findtime = 600
bantime = 7200
maxretry = 5

and i have on filter very easy :

[Definition]
failregex =.*Failed Login.*from <HOST>

My ip is detected and banned but i have on problem with iptables

I don’t understand why iptables say : iptables v1.8.7 (nf_tables): Couldn’t load match `multiport’:No such file or directory

does anyone know how to solve the problem ?
