# request_timeout

> The request exceeded the server time limit

| | |
| - | - |
| **HTTP status** | `504 Gateway Timeout` |
| **Error code** | `request_timeout` |
| **Resolve action** | None; narrow the request and retry |

## What happened

The request did not finish inside the server's per-request time limit: **60 seconds** for a standard or premium-tier request, **15 seconds** for a free-tier one. The 15-second limit also applies on every endpoint to requests from anonymous, crawler, or unentitled Radar sessions, including Smart Search. It fires when a request's own work, usually a database query, runs long: an unusually broad filter, a cold cache, or a database under load.

Smart Search's `submit` and `read` endpoints use a longer **120-second** limit instead of the standard 60 seconds, to cover the LLM routing and answer-generation work those requests do.

## How to fix

Retry with a narrower request: a smaller `limit`, a tighter date window, or a more specific filter. If every request to an endpoint times out however narrow it is, the endpoint itself is degraded; check [status.particle.pro](https://status.particle.pro) or contact support.
