Traefik不会仅加载域或www子域的“让我们加密证书”

Question

有点奇怪：对我来说，Traefik适用于app.example.com或traefik.sys.example.com等所有子域，但不适用于www.example.com或example.com。 traefik docker日志中没有错误表明该错误。我想要的是在另一个docker中部署一个简单的Flask网络服务器，该服务器将在example.com上通过以下docker-compose服务：

version: '3.3'

services:
  flask:
    image: registry.gitlab.com/myname/my_website:latest
    ports:
      - 5050:5050
    networks:
      - traefik-public
    deploy:
      labels:
        - traefik.frontend.rule=Host:example.com
        - traefik.enable=true
        - traefik.port=5050
        - traefik.tags=traefik-public
        - traefik.docker.network=traefik-public
        # Traefik service that listens to HTTP
        - traefik.redirectorservice.frontend.entryPoints=http
        - traefik.redirectorservice.frontend.redirect.entryPoint=https
        # Traefik service that listens to HTTPS
        - traefik.webservice.frontend.entryPoints=https
networks:
  traefik-public:
    external: true

我的docker-compose文件用于Traefik设置：

version: '3.3'

  consul-leader:
    image: consul
