Briefly, this error occurs when Elasticsearch fails to authenticate a user or process trying to perform an action. This could be due to incorrect credentials, expired tokens, or misconfigured roles and permissions. To resolve this, ensure that the correct credentials are being used, refresh any expired tokens, and verify that the user or process has the necessary permissions to perform the requested action.
