Traefik让我们加密OVH域名

我在Scaleway上有一个VPS，我正在运行docker，我正在努力让Let's Encrypt与Traefik一起工作 . 这是我的traefik.toml：

defaultEntryPoints = ["http", "https"]
debug = true
logLevel = "DEBUG"

[web]
  address = ":8080"
    [web.auth.basic]
    users = ["admin:$apr1$CXbUFy59$gnQY50uMvzc3Q5tnhA2ZZ."]

[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 = "viatecnologia.it"
watch = true
exposedbydefault = false

[acme]
email = "admin@viatecnologia.it"
storage = "acme.json"
entryPoint = "https"
onHostRule = true
  [acme.dnsChallenge]
  provider = "ovh"
  delayBeforeCheck = 0
onDemand = false

[[acme.domains]]
  main = "viatecnologia.it"
  sans = ["www.viatecnologia.it"]
  sub = "monitor.viatecnologia.it"

这是我的docker-compose：

version: "3"

services:
  traefik:
    container_name: traefik
    image: traefik
    volumes:
      - $PWD/traefik.toml:/etc/traefik/traefik.toml
      - $PWD/acme.json:acme.json
      - /var/run/docker.sock:/var/run/docker.sock
    ports:
      - "80:80"
      - "443:443"
    labels:
      - traefik.frontend.rule=Host:monitor.viatecnologia.it
      - traefik.port=8080
    environment:
      - OVH_ENDPOINT=ovh-eu
      - OVH_APPLICATION_KEY=fdfdsfa
      - OVH_APPLICATION_SECRET=fdsafsafda
      - OVH_CONSUMER_KEY=fdasfasdfa
    networks:
      - proxy


networks:
  proxy:
external: true

当我运行docker-compose时，我得到了这个错误

我在https://eu.api.ovh.com/createApp/上创建了一个应用程序，但它告诉我凭据不存在 . 我在他们的tutorial中创建了令牌吗？我忘记了什么吗？

有帮助吗？
