HTTP 404 Not Found
The resource doesn't exist.
What HTTP 404 Not Found means
404 Not Found means the server couldn't find anything at the requested URL. The resource may never have existed, may have been moved, or the URL may simply be wrong. It says nothing about whether the resource might exist later.
Which category is it?
404 is a 4xx code — Client error. 4xx means the request has a problem the client must fix — bad syntax, missing authentication, or a resource that isn't there. It's the caller's responsibility.
Common causes
- Mistyped or outdated URL
- The resource was deleted or moved without a redirect
- A route that isn't registered on the server
How to fix it
- Double-check the URL for typos
- Add a 301 redirect if the resource moved
- Verify the route exists and is deployed
