HTTP 202 Accepted vs 504 Gateway Timeout
HTTP 202 (Accepted) is a 2xx Success response, while 504 (Gateway Timeout) is a 5xx Server Error response. 202 indicates that the request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon. In contrast, 504 means that the server, acting as a gateway or proxy, did not receive a timely response from the upstream server.
