HTTP 408 Request Timeout is a client error-class status code defined in RFC9110. The server timed out waiting for the request.
Client-error responses signal that the problem is on the requesting side: the request is malformed, unauthorized, or aimed at something that isn't there. On the wire, the response begins with the status line HTTP/1.1 408 Request Timeout.
