Traefik-无法获取让我们为域加密的证书=> acme http挑战超时

Question

我正在尝试使用加密来保护trafik服务的网站。但是，在测试acme挑战时失败。

time="2019-02-07T23:23:35Z" level=error msg="Unable to obtain ACME certificate for domains \"git.redacted.be\" detected thanks to rule \"Host:git.redacted.be\" : unable to generate a certificate for the domains [git.redacted.be]: acme: Error -> One or more domains had a problem:\n[git.redacted.be] acme: error: 400 :: urn:ietf:params:acme:error:connection :: Fetching http://git.redacted.be/.well-known/acme-challenge/I_44HUy2IqyYZk-6GmfWxtm7Uunx_wid9rgHpXkhZcM: Error getting validation data, url: \n"

该服务器可从互联网上公开使用（如果我转到http://git.redacted.be，则将其重定向到https，并且我可以配置我的git服务器），并且也可以通过traefik和码头工人。

当我手动导航到提到的URL（.well-known / acme-challenge / ...）时，请求超时，但是在traefik中登录显示：Error getting challenge for token: cannot find challenge for

我已经尝试了https://github.com/containous/traefik/issues/2763中提到的一些解决方法（禁用IPv6并使用traefik：alpine）

这是我的设置：

Traefik docker-compose.yml

version: '3.2'
services:
  traefik:
    image: traefik:alpine # The official Traefik docker image
    command: --api --docker --logLevel=info # Enables the web UI and tells Tr ik to listen to docker
    restart: unless-stopped
    ports:
      - "81:80"     # The HTTP port
      - "444:443"
      - "18080:8080" # The Web UI (enabled by --api)
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./traefik.toml:/traefik.toml
      - ./acme.json:/acme.json
    networks:
      - traefik
    logging:
      driver: "json-file"

networks:
  traefik: 
    external:
      name: traefik

Traefik.toml

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 = "redacted.be"
watch = true
exposedByDefault = false

[acme]
email = "ronald@redacted.be"
storage = "acme.json"
entryPoint = "https"
caServer = "https://acme-staging-v02.api.letsencrypt.org/directory"
onHostRule = true
  [acme.httpChallenge]
  entryPoint = "http"

我的git服务器的docker-compose：

version: '3.2'
services:
  gogs:
    restart: unless-stopped
    image: gogs/gogs
    volumes:
      - ./data/db:/data/db
      - ./data/git:/data/git
      - ./data/gogs:/data/gogs
    networks: 
      - gogs
      - traefik
    ports:
      - "10022:22"
      - "3000:3000"
    labels:
      - "traefik.port=3000"
      - "traefik.frontend.rule=Host:git.redacted.be"
      - "traefik.docker.network=traefik"

networks:
  gogs:
  traefik: 
    external:
      name: traefik

知道我在做什么错吗？
