To resolve this, ensure that the Elasticsearch cluster has a valid license. If it’s expired, you need to update it. Also, check your network settings to ensure that Elasticsearch can communicate with the license server. If the issue persists, you may need to reinstall Elasticsearch or contact support for further assistance.
