ElasticsearchException connection refused

Elastic Stack Elasticsearch

Hello,

I have this error when I try to search for something using elasticsearch

Caused by: org.springframework.data.elasticsearch.UncategorizedElasticsearchException: java.util.concurrent.ExecutionException: java.net.ConnectException: Connection refused; nested exception is ElasticsearchException[java.util.concurrent.ExecutionException: java.net.ConnectException: Connection refused]; nested: ExecutionException[java.net.ConnectException: Connection refused]; nested: ConnectException[Connection refused];

I use:

  • spring-data-elasticsearch version 4.4.0
  • elasticsearch 7.17.6

I need to know if there’s a compatibility between the two librairies. And by any chance, is this error due to the fact that I am using version 7.17.6 and not 7.17.3 ?
Because in the compatibility matrix I have this:
