Seems your client IP address was blocked in iptables (triggered by Fail2ban). Please check iptables block list.

Fail2ban scans several log files (check /etc/fail2ban/jail.local), if client reproduced same error for several times (defined in 'maxretry ='), fail2ban will call iptables to block client IP address.

For more details, please check http://www.fail2ban.org
