-I use openJdk 1.8


*-Elasticsearch 6.8.1+Logstash 6.8.1+mysql *


*-My file elasticsearch/elasticsearch.yml : *

The error is in the output elasticsearch. Connection refused but the configuration of elasticsearch is great and listen on this port:

tcp6 0 0 :::9200 :::* LISTEN 18817/java
tcp6 0 0 :::9300 :::* LISTEN 18817/java
