Please make sure when connect to elastic search you must enter the port to 9300 instead of 9200 with cluster name and ip

I did this, but I don't know where the problem is. The executive order is all but the node, thank you.

This code works for me: https://github.com/dadoonet/legacy-search/blob/01-direct/src/main/java/fr/pilato/demo/legacysearch/dao/ElasticsearchDao.java#L48

Make sure that you set cluster name if you changed it and if you are running your code on another machine that you changed network.host

yes！i am sure changed !thank you very much. i will have a try.
