Too many failed attempts — your IP has been banned
After repeated failed password logins, the client IP is blocked (AUTH_LOGIN_IP_BANNED). Product: contact support.
Why this happens
enforceFailedLoginIpBanIfNeeded / isLoginBlockedByIpBan — anti-brute-force. Distinct from account-level bans and from captcha-required soft limits.
Diagnose and fix
1. Member: wait or contact support; try from another network if appropriate.
2. Admin: Banned users / IPs — review/remove the IP ban; check Whitelisted IPs if staff need access.
3. Review Max login attempts per hour (and related) thresholds.
4. After unblock, member should use correct credentials or forgot-password (not more guessing).
