I'm running elasticsearch in docker desktop(container) and try to connect with web application. Above log showing under web application logs. Below is my docker compose file. ``` version: '3.6' services: geoportal: build: geoportal ports: - "8080:8080" hostname: geoportal environment: - es_cluster=elasticsearch - es_node=elasticsearch # volumes: # - "./local/harvester:/root" links: - elasticsearch:elasticsearch networks: - default elasticsearch: image: elasticsearch:5.6 container_name: elasticsearch hostname: elasticsearch ports: - "9200:9200" - "9300:9300" volumes: - esdata1:/usr/share/elasticsearch/data environment: - "ES_JAVA_OPTS=-Xms750m -Xmx750m" - bootstrap.memory_lock=true - discovery.type=single-node - cluster.name=elasticsearch # - network.host=127.0.0.1 # - transport.host=0.0.0.0 - xpack.security.enabled=false ulimits: memlock: soft: -1 hard: -1 networks: - default networks: default: external: name: geoportal volumes: esdata1: driver: local ``` ---

Welcome! Not sure what the problem is here. But anyway, do not use the TransportClient. It will be removed in the next major version. Just use the REST Client. ---

Sure, Thanks for your comments. But I don't have any control to change TransportClient. Also I've tried many methods to make a connection and found Elasticsearch is not connected to the private or generated network in Docker. If I ran the same out of Docker working fine. ---

Does it mean that you are not writing the Java code? ---
