NPM changed its log format. Old filters expected classic nginx format: PROXY_IP - - [date] "METHOD PATH" STATUS BYTES "REF" "UA" [Client IP] Actual current format: [date] - STATUS STATUS - METHOD SCHEME HOST "PATH" [Client IP] [Length N] [Gzip N] [Sent-to IP] "UA" "REFERER" fail2ban strips the timestamp before applying failregex, so patterns must match the post-strip line (no ^ timestamp prefix). All three filters updated: http-errors, npm-probe, badbot. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# ── 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.
