HTTP 408 Request Timeout indicates the server waited too long for the client to send the complete request. The server is closing the connection because the client didn't finish transmitting within the allowed time. This is not about server processing time (which would be a 504 from a proxy) — it's about the client being too slow to send its request. Servers send 408 to free up connections from idle or stalled clients.
Response includes the status code, standard headers (including Content-Type), and a small diagnostic JSON body describing the request and returned status.
