linux – fail2ban action error: fail2ban.action: ERROR iptables -w -D INPUT -p tcp -m multiport –dports ssh


I get the following error in logs:

fail2ban.action[7487]: ERROR iptables -w -D INPUT -p tcp -m multiport --dports ssh -j f2b-sshd # 012iptables -w -f f2b-sshd # 012iptables -w -x f2b-sshd -stdout: b & # 39; # 39;

How can I fix this?

My jail.local:
