Briefly, this error occurs when the current master node in an Elasticsearch cluster loses its status due to network partitioning, node failure, or a new node with a higher term is elected as master. To resolve this, ensure all nodes are running and network connectivity is stable. If the issue persists, consider increasing the ‘discovery.zen.minimum_master_nodes’ setting to a higher value to prevent split-brain scenarios. Also, check the cluster’s health and logs for any anomalies. If a new master node is causing the issue, verify its configuration and suitability for the master role.
