# HTTP 404 Not Found in AWS S3

**Platform** — Amazon S3 — object storage, often fronting a static site or CDN.

**Where it surfaces** — S3 access logs, CloudFront distribution logs, or the browser response headers (`x-amz-request-id`).

## Cause on this platform

Key doesn't exist, or the caller has `s3:ListBucket` denied (S3 returns 404 to hide existence).

## Fix on this platform

Confirm the object key exactly (case-sensitive), then grant `s3:ListBucket` on the parent prefix if you want a true 404 vs 403 signal.


## Generic reference

The requested resource could not be found on the server — the page may have been deleted, moved, or the URL was typed incorrectly.
