404 Not Found
The server found nothing at the target URL, or does not want to reveal that something exists there. It says nothing about whether the absence is temporary.
4xx · Client error
Typical causes
A typo or stale link, a deleted page, a missing route in the application, or a single-page app route requested directly from the server.
On Bex
On a Bex static site, a 404 on the homepage usually means the publish path or index.html location is wrong; 404s on nested client-side routes need a rewrite to /index.html.
Defined in RFC 9110, §15.5.5
