Briefly, this error occurs when Elasticsearch is unable to find a network address for a node. This could be due to incorrect configuration settings or network issues. To resolve this, you can check your Elasticsearch configuration file (elasticsearch.yml) to ensure that the network settings are correct. Also, verify that your network is functioning properly. If you’re using a cloud service, ensure that the correct security groups and access permissions are in place. Lastly, if you’re using Docker, ensure that the network settings are correctly configured in your Dockerfile or docker-compose file.

                    logger.warn("no network address found. ignoring [{}]..."; instance.getInstanceName());

                try {
