ACCOUNT_VALIDATION_ERROR on Make.com: Invalid connection — please reauthorize app or InvalidAccessTokenError causing scenario execution to stop and scheduling to be automatically disabled. — Root cause: Stored OAuth tokens or API credentials have expired, been revoked, or become invalidated due to a password change, security update, or token idle timeout on the third-party app. When this happens, Make cannot authenticate requests, immediately throwing an authentication error and halting scenario scheduling to protect data integrity. — If reauthorizing the connection fails repeatedly or the third-party app rejects Make's OAuth requests, contact Make Support through the help widget with your organization name, scenario ID, and a full screenshot of the execution history error log.
