PR https://github.com/hastic/hastic-server/pull/931 introduced HASTIC_SERVER_URL variable to configure URL to bind websockets (default value is ws://localhost:8002).
The problem is: the default value doesn't work in Docker because nothing outside the container can query container's localhost.
We should add HASTIC_SERVER_URL to docker-compose.yml with default ws://server:8002 value
