# ── NPM access log format (current) ──────────────────────────────────────────
# [DD/Mon/YYYY:HH:MM:SS +0000] - STATUS STATUS - METHOD SCHEME HOST "PATH"
#   [Client REAL_IP] [Length N] [Gzip N] [Sent-to IP] "UA" "REFERER"
#
# fail2ban strips the timestamp before applying failregex, leaving:
#   " - STATUS STATUS - METHOD SCHEME HOST "PATH" [Client IP] ... "UA" ..."
#
# UA appears after [Sent-to ...] so .* is used between <HOST> and the UA match.
#
# Test against your logs:
#   fail2ban-regex /nginx-logs/proxy-host-1_access.log /etc/fail2ban/filter.d/badbot.conf
