HTTP 503. Nothing reached the broker.

**Likely causes:**

- The terminal is starting or reconnecting.
- The broker server is down or rejected the login.

**What to do:** Retry with backoff and check the account's health endpoint.

**Retry:** Yes. Nothing happened (or it was a read), so repeat it, after `Retry-After` when present.
