Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which analyzes 2 JSON files to detect many errors.

Briefly, this error occurs when Elasticsearch is unable to retrieve a snapshot from a repository. Snapshots are used to create backups of data, and a failure to retrieve a snapshot can result in data loss or corruption. The cause of this error can be due to an incorrect repository configuration, Elasticsearch does not have permission to access the repository, or a corrupted snapshot. To resolve this error, you can check the repository configuration to ensure that it is correct and that Elasticsearch has permission to access the repository. Also, you can verify that the snapshot exists in the repository and is not corrupted. Additionally, you can increase the snapshot repository’s retention policy to ensure that snapshots are available when needed.
