You should have a line like `-A INPUT -p tcp -m multiport --dports MYSSHPORT -j f2b-sshd`

Had more or less the same issue last year (because I done a stupid thing when I tried to add a jail) =\> [SSH : Multiple tentatives de connexion malgré fail2ban - #5 by Kit](https://forum.yunohost.org/t/ssh-multiple-tentatives-de-connexion-malgre-fail2ban/20397/5)

Let’s recheck properly :

- `cat /etc/fail2ban/jail.d/yunohost-jails.conf` : is the sshd jail in the output ? Is the ssh port the new one ?
- `yunohost settings get security.ssh.port` : let’s double-check if the right port is monitored.
- `yunohost service status yunohost-firewall fail2ban`: are the firewall and f2b services running ?
- Did you tried to restart the firewall and f2b services ?
