description: Authentication is temporarily unavailable.

**HTTP status:** `503`.

The capability credential could not be checked because its backing store did not answer. Nothing was read or changed.

## Troubleshooting

- Retry the same request with bounded backoff; nothing was recorded.
- If it persists, contact support and quote the request\_id.
