429 Too Many Requests — Nginx Rate Limited

Apa penyebab error ini

The limit_req module is rejecting requests that exceed the configured rate limit.

Cara memperbaikinya

Reduce request frequency. Increase the rate limit in limit_req_zone. Add burst parameter for temporary spikes.

# Rate limiting config
limit_req_zone $binary_remote_addr zone=one:10m rate=10r/s;
location / {
  limit_req zone=one burst=20 nodelay;
}
