404 Not Found nginx

nginx looked for the page on disk, where the configuration says, and it is not there.

Every page but some, or a whole section, is a dead end.

Seeing it on someone else’s site?

• The address may be wrong or out of date; try the site's home page.

Why it happens, if it is your site

• root or alias pointing at the wrong folder, or alias used where root was meant (they join paths differently).
• A single-page app without try_files $uri $uri/ /index.html;, so any address but the home page is a 404 on reload.
• WordPress or another PHP app without try_files $uri $uri/ /index.php?$args;, so pretty permalinks 404.
• The request matched a different location block than intended.

How to fix it

1. The error log's open() "/path" failed (2: No such file or directory) shows the exact path nginx tried; compare it with where the file is.
2. Add the try_files line your app needs.
3. Test with nginx -t, reload, and request the path again.

Whose problem it is

Usually the server that answers the request.

Often seen with

• 404 Not FoundThe server has nothing at this address: a page or file that was moved, deleted, or never existed.
• 403 Forbidden (nginx)nginx found the path but is not allowed to serve it.
