Too many captcha reloads — try again later
/api/captcha/challenge (or equivalent reload) returned 429 after too many challenge fetches.
Why this happens
Abuse protection on captcha challenge generation. Rapid refresh/reload of the widget triggers this. Distinct from Captcha verification failed (wrong/expired solve).
Diagnose and fix
1. Wait a few minutes; reload the page once; complete the captcha carefully.
2. Admin: confirm Captcha provider keys are valid so users are not stuck reloading.
3. Check Captcha on login / Captcha on registration only where needed.
4. Distinct from login failure captcha prompt (Too many failed sign-in attempts — complete the captcha).
