Docker Traefik+；Nextcloud导致网关损坏

我有3个服务正在运行。 mariadb&nextcloud实例：

version: '2.1'

volumes:
  nextcloud:
  db:

services:
  db:
    image: mariadb
    volumes:
      - db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=my_root_password
      - MYSQL_PASSWORD=my_password
      - MYSQL_DATABASE=my_database
      - MYSQL_USER=my_user
  app:
    image: nextcloud
    restart: always
    networks:
      - web
      - default
    ports:
      - 9000
    labels:
      - "traefik.backend=app"
      - "traefik.docker.network=web"
      - "traefik.frontend.rule=Host:my_host"
      - "traefik.enable=true"
      - "traefik.port=9000"
      - "traefik.default.protocol=http"

networks:
  web:
    external: true

以及traefik服务：

version: '2'

services:
  traefik:
    image: traefik:1.5.4
    restart: always
    ports:
      - 80:80
      - 443:443
    networks:
      - web
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /opt/traefik/traefik.toml:/traefik.toml
      - /opt/traefik/acme.json:/acme.json
    container_name: traefik

networks:
  web:
    external: true

此traefik实例正在使用此配置文件：

debug = false

logLevel = "ERROR"
defaultEntryPoints = ["https","http"]

[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]
  address = ":443"
  [entryPoints.https.tls]

[retry]

[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "my_host"
watch = true
exposedByDefault = false

[acme]
email = "my_email"
storage = "acme.json"
entryPoint = "https"
onHostRule = true
[acme.httpChallenge]
entryPoint = "http"

现在，当我转到我的主机时，它会重定向到HTTPS，但随后它只会显示

坏网关

，而不会显示其他内容。它应该显示nextcloud web应用程序。有人知道为什么会这样吗？我正在使用docker compose up-d命令运行compose文件。

现在可能已经太晚了，但我自己也遇到了这个问题，所以我发布了一个解决问题的答案。

Nextcloud在Traefik试图连接的容器IP地址上公开端口80。因此，您错误地为“traefik.port”标签指定了端口。将其从9000更改为80

你有没有想过？
