尝试访问 traefik 仪表板时出现 404

我尝试以一种简单的方式通过子域访问 traefiktraefik (traefik.DOMAIN.com）。当我获得访问权限后，SSL 证书功能良好，但无法访问仪表板（404 错误）

docker-compose.yml

version: '3'

services:
  reverse-proxy:
    image: traefik:v2.2
    container_name: traefik
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - $PWD/traefik.toml:/etc/traefik/traefik.toml
      - $PWD/acme.json:/acme.json
    restart: always
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.api.rule=Host(`traefik.DOMAIN.com`) && (PathPrefix(`/api`) || PathPrefix(`/dashboard`))"
      - "traefik.http.routers.api.service=api@internal"
      - "traefik.http.routers.api.entrypoints=websecure"
    networks:
      - web
networks:
  web:
    external: true

traefik.toml

[api]
  dashboard = true

[entryPoints]
  [entryPoints.web]
    address = ":80"
    [entryPoints.web.http]
      [entryPoints.web.http.redirections]
        [entryPoints.web.http.redirections.entryPoint]
          to = "websecure"
          scheme = "https"

  [entryPoints.websecure]
    address = ":443"
      [entryPoints.websecure.http.tls]
        certResolver = "default"

[providers]
  [providers.docker]
    watch = true
    exposedByDefault = false
    network = "web"

[certificatesResolvers]
  [certificatesResolvers.default]
    [certificatesResolvers.default.acme]
      email = "[email protected] /cdn-cgi/l/email-protection"
      storage = "acme.json"
      caServer = "https://acme-v01.api.letsencrypt.org/directory"
    [certificatesResolvers.default.acme.tlsChallenge]

关于如何实现这项工作有什么想法吗？我希望最终能够在子域上安装 owncloud

在阅读文档并在调试模式下检查日志后，我能够使其工作。这key这是尾随的/这是mandatory.
