My /etc/fail2ban/filter.d/wordpress-auth.conf:

[Definition]
failregex = <HOST>.*POST.*xmlrpc\.php.* 499

In my /etc/fail2ban/jail.conf:

[wordpress]
enabled  = true
port     = http,https
filter   = wordpress-auth
logpath  = /var/log/nginx/access.log
maxretry = 3
bantime  = 86400

I've restarted fail2ban, but I'm not seeing any [wordpress] in my /var/log/fail2ban.log. What am I doing wrong?

nginx wordpress fail2ban

    Right okay it seems it is working, it was just slow to react to the logs.
