HTTP 414 URI Too Long

Client Error

The request URL exceeds the server's limit — usually a symptom of stuffing data into the query string.

Defined in RFC 9110

Common causes

  • Long query strings (filters, encoded payloads, GET abuse)
  • Redirect loops appending parameters each pass

How to fix it

  1. Move the data into a POST body

  2. Break redirect loops that grow the URL

  3. Raise the proxy's URL length limit only as a last resort

413 Content Too Large

The request body exceeds what the server is willing to process. Formerly called 'Payload Too Large'.

400 Bad Request

The server can't or won't process the request because the client sent something malformed — invalid JSON, bad query parameters, broken headers or framing.
