Briefly, this error occurs when Elasticsearch is unable to automatically determine the publish port due to multiple bound addresses. This can happen when the node is configured to bind to multiple network interfaces. To resolve this issue, you can specify a single network interface in the Elasticsearch configuration file (elasticsearch.yml) using the ‘network.host’ setting. Alternatively, you can explicitly set the ‘http.publish_port’ or ‘transport.publish_port’ depending on your setup. This will help Elasticsearch to identify the correct publish port.
