Stale History

A horizon server may be configured to reject historical requests when the history is known to be further out of date than the configured threshold. In such cases, this error is returned. To resolve this error (provided you are the horizon instance’s operator) please ensure that the ingestion system is running correctly and importing new ledgers.
