Description

I started running a three-container setup on my server as follows:

cp .env.docker.example .env
docker compose -f docker-compose.three-container.yml up -d

Everything went smoothly with pulling images and running the containers. I set up some port forwards to access Hermes on my local machine. However, only the web UI dashboard at http://localhost:8787 is accessible, and I can't open the Hermes dashboard at http://localhost:9119. Direct access via the server's IP address also doesn't work. After opening the web UI dashboard, I get a Hermes agent is not responding error. Docker ps confirms that all three containers are up and running.

Have I missed any steps?

Contributor guide

Research direction
Inspect the Docker Compose configuration to understand how the WebUI service connects to the Hermes agent. Find where the 'Hermes agent is not responding' error is generated in the codebase and trace back to the expected host/port configuration. Check container logs and try to access the Hermes service directly from within the WebUI container to verify network connectivity.
