A required downstream service did not respond in time.

## Response


```http
HTTP/1.1 504 Gateway Timeout
Content-Type: application/problem+json
Retry-After: 60

{
  "type": "https://docs.apiera.io/problems/gateway-timeout",
  "title": "Gateway Timeout",
  "status": 504,
  "detail": "A required downstream service did not respond in time. Please try again later.",

  "correlationId": "550e8400-e29b-41d4-a716-446655440000"
}
```

## How to Handle

1. Check the `Retry-After` header (60 seconds)
2. Wait before retrying
3. Implement exponential backoff for multiple failures


This is typically a temporary issue. If it persists, contact support with the `correlationId`.
