Too many registration attempts — try again later
rateLimitRegister blocked POST /api/auth/register (429). Product: try again later.
Why this happens
Per-IP signup abuse protection. Distinct from Registration is currently disabled and from mail-host / captcha failures.
Diagnose and fix
1. Wait and retry once; UI may show a seconds countdown via Too many attempts — try again in about {seconds} seconds.
2. Shared NAT/VPN: many users may share a limit — wait or use another network.
3. Admin: tune register rate limits if needed; confirm Registration enabled.
4. Complete captcha correctly to avoid wasted attempts.
