Cannot visit grafana monitor

After successfully run the test node, I cannot visit grafana monitor, (http://localhost:3000 )although I can see port 3000 has been exposed in docker-composer.yml:

grafana:
image: grafana/grafana:7.3.7
container_name: grafana
volumes:
- grafana_data:/var/lib/grafana
- ./grafana/provisioning:/etc/grafana/provisioning
environment:
- GF_SECURITY_ADMIN_USER={ADMIN_USER:-admin} - GF_SECURITY_ADMIN_PASSWORD={ADMIN_PASSWORD:-admin}
- GF_USERS_ALLOW_SIGN_UP=false
- GF_SECURITY_DISABLE_BRUTE_FORCE_LOGIN_PROTECTION=true
- postgres_host={DB_HOST:-postgres} - postgres_user={DB_USER:-graph-node}
- postgres_pass={DB_PASS:-db-password} - postgres_db={GRAPH_NODE_DB_NAME:-graph-node}
- VIRTUAL_HOST={GRAFANA_HOST} - VIRTUAL_PORT=3000 - LETSENCRYPT_HOST={GRAFANA_HOST}
- GF_INSTALL_PLUGINS=fifemon-graphql-datasource
- subgraph_endpoint=${SUBGRAPH_ENDPOINT:-https://gateway.testnet.thegraph.com/network}
restart: unless-stopped
expose:
- 3000
networks:
- monitor-net
labels:
org.label-schema.group: “monitoring”

I can see it’s up: grafana /run.sh Up 3000/tcp

Too tired playing with indexer, still don’t know how to setup cost model, query fee cut and so on.
