HTTP_E_STATUS_NOT_FOUND

HTTP_E_STATUS_NOT_FOUND maps to HTTP 404 Not Found. The origin server did not find a current representation for the target resource or is unwilling to disclose that one exists.

What to check

Verify the final URL after redirects, including path casing, percent encoding, query parameters, and virtual host selection.
Check routing, reverse-proxy rewrite rules, deployment paths, and API version prefixes.
Do not assume the resource was permanently removed; 404 does not make that claim. Use 410 when the server intends to signal likely permanent removal.
