Treafik - adding routing from different stack

Traefik Traefik v2 (latest)
1

Hello ,

traefik managing / routing all containers running from same stack(docker-compose1),
all belong to "dockers_default" network.

on other stack - docker-compose2,
i added traefik labels by same fashion i use in first stack + bound these stack also to "dockers_default" network .
And it doesn't work - Getting error 502/522 on browser.
couldn't find any error on traefilk/access.log
( added CNAME on cloudflare as usual)

1.What im doing wrong?
from traefik dashboard i do see it added on routing same for load balancer.

2.on docker-compose 2 :
I'm running webserver which provide different functionalities on each path i.e:
192.168.1.112:8111/mig
192.168.1.112:8111/tig
i would like to sperate routing rules:

i.e:
mig.MYDOMAIN.com will route to --> 192.168.1.112:8111/mig
tig.MYDOMAIN.com will route to --> 192.168.1.112:8111/tig

I saw some traefik configuration which support similar cases but all coming from same stask,
i'd like to keep current routing on docker-compose1 ,
on the other docker-compose , add the option for routing per each subdomain as explain in#2.

docker-compose1.yml
Traefik configured as

      traefik.http.routers.traefik.middlewares: auth
      traefik.http.middlewares.auth.basicauth.users: ${TRAEFIK_USER}:${TRAEFIK_PASS}

All the dockers which configure by this docker compose ,routing by traefik perfectly with no issue ,
On the other stack ,
docker-compsoe_2.yml
i added only traefik labels as:

version: '3.7'
services:
  webserver:
    build: .
    container_name: webserver
    command: uvicorn main:app --host 0.0.0.0 --port 8000 --reload
    volumes:
      - ./backend/webserver:/webserver
    ports:
       - "${WEBSERVER_PORT:-8111}:8000"
    depends_on:
        - mongo_db
    networks:
      - dockers_default
    labels:
      traefik.enable: true
      traefik.http.routers.mig.rule: Host(`mig.${DOMAINNAME}`)
      traefik.http.routers.mig.entrypoints: websecure
      traefik.http.services.mig.loadbalancer.server.port: 8111
      COMPOSE_PATH: ${PWD}

## here i'd like adding the routing functionality mention in #2

networks:
  dockers_default:
    external: true
