Docker-Compose Deployment Help - Unable to connect to Elasticsearch node

Graylog Central (peer support)

I’m trying to deploy Graylog using the following Docker-Compose method:

The only thing I’ve changed is the volume paths to map to the correct directory on my host and updated the .env file with the necessary values.

When I deploy the container, I get the following error:

2022-12-18 14:41:32,129 ERROR: org.graylog2.storage.versionprobe.VersionProbe - Unable to retrieve version from Elasticsearch node: Failed to connect to opensearch/192.168.208.3:9200. - Connection refused.

Hello @a7ebouovue8v

I’m kind of familiar with Docker installs, and the one thing I dont see is the network configurations in the docker-compose.yml file.

networks:
