Briefly, this error occurs when Elasticsearch is unable to identify the node due to a mismatch in the node ID or cluster name. This could be due to configuration issues or network problems. To resolve this, you can check the Elasticsearch configuration files for any discrepancies in the node ID or cluster name. Ensure that the network connectivity between the nodes is stable. Also, restarting the Elasticsearch service can help in refreshing the node’s state. If the issue persists, consider rejoining the node to the cluster.

This guide will help you check for common problems that cause the log ” node name [{}]; node ID [{}]; cluster name [{}] ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: node, cluster.
