HTTP 414 URI Too Long

414 URI Too Long

The server refused the request because the target URI is longer than the server is willing to interpret.

414 URI Too Longnetworking

Observed message

414 URI Too Long

Why it happens

  • The URL or query string is too long for the server or proxy limits.
  • A GET request is carrying too much encoded state in the URL.
  • Redirect loops or malformed client logic keep expanding the URI.

How to fix it

  1. Shorten query parameters and encoded state in the URL.
  2. Move large request data from the URI into the request body where appropriate.
  3. Check for redirect loops or client bugs that keep lengthening the URL.
