Multiple Dockerized angular apps on a single host

I'm attempting to host 2 containers of the same image of a web console pointed to different environments on a single host and route to them with a Traefik container. The problem is, the second container is not accessible. I keep getting Bad Gateway.

Navigating to the IP with the port of the second container fails, but the port mapping configuration appears fine. There are no logs in the second container.

docker-compose

  console:
    container_name: console
    image: REDACTED
    environment:
      API_URL: "REDACTED-PRD"
    ports:
      - 4200:4200
    labels:
      - traefik.port=4200
      - traefik.frontend.rule=Host:dev.REDACTED.com
  console-prd:
    container_name: console-prd
    image: REDACTED
    environment:
      API_URL: "REDACTED-DEV"
    ports:
      - 4300:4200
    labels:
      - traefik.port=4300
      - traefik.frontend.rule=Host:app.REDACTED.com
  traefik:
    container_name: traefik
    image: traefik:1.7.10-alpine
    ports:
      - 80:80
      - 443:443
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./traefik.toml:/etc/traefik/traefik.toml:Z```

ipaddr:4300 gets bad gateway. Traefik logs:
