414 URI Too Long — Nginx URI Too Long

Qué causa este error

The URL is longer than large_client_header_buffers allows. This can happen with extremely long query strings.

Cómo solucionarlo

Increase large_client_header_buffers. Reduce the URL length. Use POST instead of GET for large data.

# Increase buffer size
large_client_header_buffers 4 32k;
