# ATTESTATION_EXPIRED

**Attestation is too old**

## What happened

The attestation timestamp is older than the freshness window (default 5 minutes). Stale attestations don't prove current TEE state.

## How to fix

Request a fresh attestation by re-running the inference call. If you cached an attestation, drop the cache and re-fetch.

## Example

```ts
// Always re-attest at request time, not on a long-lived cache
const fresh = await compute.inference({ messages });
```
