408 Request Timeout
4xx Client Error
RFC 9110
You took too long. The server gave up waiting.
What 408 Request Timeout means {#what}
The server closed an idle connection because the client didn’t send a complete request in time. Some servers send this proactively on idle connections even without a pending request. Not necessarily an error — the client can simply retry.
When you’ll see a 408 {#when}
- Slow network conditions
- Client started a request but stalled
- Server cleaning up idle connections
