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:

The traefik port should be 4200 in the labels as well. Traefik didn't use the published port
