ERR_ABORTED 🟨 JavaScript

net::ERR_ABORTED 404 (Not Found)

The browser cancelled the request — often because it returned an error (404) or the page navigated away.

Seen on: JavaScript

Meaning

In DevTools, ERR_ABORTED with a status (404/403) means the resource failed; without status it often means the request was cancelled by navigation, a newer request, or AbortController.

Common causes

  • Missing asset (404)
  • Navigation or form submit cancelling pending requests
  • AbortController aborting fetches
  • Media requests cancelled by the browser

⚡ Quick fix

  1. Check the status shown next to ERR_ABORTED
  2. Fix asset paths
  3. Ignore cancellations caused by intentional navigation

Detailed fix by platform

JavaScript

  1. fetch(url, { signal }).catch(e => { if (e.name !== 'AbortError') throw e; });

How to diagnose

  1. Status — Is there a status code?
  2. Cause — Navigation or abort?
