Hello, I set traefik server but dashboard page always 404. even not show basic auth.
I don't know what I wrong.

  [entryPoints.web]
    address = ":80"
    [entryPoints.web.http.redirections.entryPoint]
      to = "websecure"
      scheme = "https"
      permanent = true
  [entryPoints.websecure]
    address = ":443"
  [entryPoints.websecure.http.tls]
    certResolver = "myresolver"

[log]
  level = "DEBUG"
[accessLog]

[api]
  dashboard = true

[providers]
  [providers.docker]
    endpoint = "unix:///var/run/docker.sock"
    exposedbydefault = false
    network = "web"

[certificatesResolvers]
  [certificatesResolvers.myresolver.acme]
    email = "<EMAIL>"
    storage = "acme.json"

  [certificatesResolvers.myresolver.acme.tlsChallenge]
