Fail2ban not banning? Common causes and fixes
Fail2ban is running but attackers are never banned. Work through the usual causes, from the wrong log backend and log path to a ban action that does not fit your firewall or a custom SSH port.
Use Fail2ban with firewalld or nftables ban actions
Make Fail2ban put its bans into the firewall your server really uses. Set banaction to firewalld rich rules or nftables, check the distribution defaults and confirm bans in the live ruleset.
