Minio and Traefik

OK, thanks.
I try to go back to a simpler way to define my minio config:

  minio:
    image: docker.io/bitnami/minio:2022
    container_name: minio
    ports:
      - '9000:9000'
      - '9001:9001'
    environment:
        - MINIO_ROOT_USER=mathieu
        - MINIO_ROOT_PASSWORD=mathieu-password
    volumes:
      - 'minio_data:/data'
    labels:
     - "traefik.enable=true"
     - "traefik.http.routers.minio.entrypoints=websecure"
     - "traefik.http.routers.minio.tls=true"
     - "traefik.http.routers.minio.rule=Host(`$MY_DOMAIN`) && PathPrefix(`/minio`)"

When I browse https://ajmr.mobiliscope.com/minio, there is a redirection to the port 9001 (http://ajmr.mobiliscope.com:9001/). There is no routing to the minio docker. What am I doing wrong ?
