Briefly, this error occurs when Elasticsearch is unable to automatically determine the HTTP 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’ setting in the configuration file to define the HTTP publish port.

" with distinct ports and none of them matched the publish address (" + publishInetAddress + "). " +
