HTTP 416 Range Not Satisfiable vs 504 Gateway Timeout
HTTP 416 (Range Not Satisfiable) is a 4xx Client Error response, while 504 (Gateway Timeout) is a 5xx Server Error response. 416 indicates that the server cannot serve the requested byte range. The Range header value is outside the resource's size. In contrast, 504 means that the server, acting as a gateway or proxy, did not receive a timely response from the upstream server.
