Traefik can't resolve domain name set via Pi-hole local DNS

Traefik Traefik v3 (latest)
1

So I have Pi-hole and Traefik both configured in Docker running as individual containers, Pi-hole pointing home.lab to my local IP 192.168.1.199. I'm using it as my domain name in the rule.Host label for services that go through Traefik's network.

compose.yml for traefik:

services:
  traefik:
    container_name: traefik
    image: traefik:v3.3
    command:
      - --log.level=DEBUG
      - --api.insecure=true
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --entryPoints.web.address=:80
      - --entryPoints.secureweb.address=:443
    ports:
      - 80:80
      - 443:443
      - 8088:8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

compose.yml for pihole:

services:
  pihole:
    container_name: pihole
    image: pihole/pihole:latest
    ports:
      - "53:53/tcp"
      - "53:53/udp"
    networks:
      - traefik_default
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.pihole.entrypoints=web"
      - "traefik.http.routers.pihole.rule=Host(`pihole.home.lab`)"
      - "traefik.http.services.pihole.loadbalancer.server.port=80"
    environment:
      TZ: 'Asia/Calcutta'
      FTLCONF_webserver_api_password: 'admin@pihole'
      FTLCONF_dns_listeningMode: 'all'
    volumes:
      - './etc-pihole:/etc/pihole'
    restart: unless-stopped
networks:
  traefik_default:
    external: true

I concluded that domain name resolution is the problem because I can access the service if the rule=Host(pihole.localhost)
