414 Request-URI Too Large: what it means and how to fix it
Find which server sent the 414 and stop the redirect or form that keeps growing the URL. Raise the nginx or Apache limit only for legitimate long URLs.
Tested on nginx 1.30.6 and Apache 2.4.70 (Apache Lounge Win64 build) on Windows 10 Pro with a Node.js 22.23.4 backend, and WordPress 7.1.4 on PHP 8.3 in Playground, November 11, 2026
