Briefly, this error occurs when Elasticsearch is unable to convert a given address to a transport address, which is necessary for node-to-node communication. This could be due to an incorrect IP address or hostname in the configuration file. To resolve this issue, you can verify the IP addresses or hostnames in your Elasticsearch configuration file. Ensure they are correct and reachable. Also, check your network settings and firewall rules to ensure they are not blocking the communication. If you’re using a cluster, ensure all nodes have the same transport module settings.
