Briefly, this error occurs when Elasticsearch encounters an issue during the election process for a new master node, typically due to network problems or node failures. To resolve this, you can check the cluster’s health and ensure all nodes are properly connected. If a node is down, restart it. If the network is the issue, check your network configurations. Also, ensure that your Elasticsearch version is up-to-date as this could be a bug that’s fixed in a newer version.
