Two entrypoints / services for one hostname

Traefik Traefik v3 (latest)
1

Trying to work out why this isn't working. I'm sure I've done this before! Error is:

ERR Router nodered cannot be linked automatically with multiple Services: ["nodered" "nr"] providerName=docker routerName=nodered

(and then vice versa):

ERR Router nr cannot be linked automatically with multiple Services: ["nodered" "nr"] providerName=docker routerName=nr

This is my docker-compose (https is port 443 and admin-secure is on port 3443)

services:
    node-red:
        image: nodered/node-red:latest
        container_name: node-red
        environment:
            - NODE_RED_ENABLE_PROJECTS=true
        volumes:
            - nodered_data:/data
        expose:
            - 1880
            - 3000
        labels:
            traefik.enable: true
            traefik.docker.network: proxy

            # ui
            traefik.http.routers.nodered.rule: Host(`nr.example.com`)
            traefik.http.routers.nodered.tls: true
            traefik.http.routers.nodered.tls.certresolver: myprovider
            traefik.http.routers.nodered.entrypoints: admin-secure

            traefik.http.services.nodered.loadbalancer.server.port: 1880

            # webhooks
            traefik.http.routers.nr.rule: Host(`nr.example.com`)
            traefik.http.routers.nr.tls: true
            traefik.http.routers.nr.tls.certresolver: myprovider
            traefik.http.routers.nr.entrypoints: https

            traefik.http.services.nr.loadbalancer.server.port: 3000

        restart: unless-stopped
        networks:
            - proxy
volumes:
    nodered_data:

networks:
    proxy:
        external: true

What am I doing wrong here?

Try to assign the service to the router, for each router.

Router and service can have the same name.

No difference unfortunately :frowning:

Share your compose file again. Note that you don’t need expose, as that’s just an indicator and you set loadbalancer.server.port.

This is my full config now (with only the host rule's domain changed). There's a couple of other bits in there for websockets which I believe I need, but I have tried without them also...
