Traefik:无法获取域的ACME证书

Question

我正在使用traefik在我的NAS上提供一些服务，使用的是https和lets。现在我注意到我的nextcloud安装的tls证书昨天晚上过期了。Traefik的日志如下：

time="2018-08-31T22:43:08Z" level=error msg="Error getting ACME client: ACME client still not built, retrying in 6.83135832s"
time="2018-08-31T22:43:15Z" level=error msg="Error getting ACME client: ACME client still not built, retrying in 12.680203952s"
time="2018-08-31T22:43:28Z" level=error msg="Error getting ACME client: ACME client still not built"

我更新到了v1.7，但现在错误不同了：

time="2018-09-01T07:42:44Z" level=error msg="Unable to obtain ACME certificate for domains \"my.domain\" detected thanks to rule \"Host:cloud.dnas.one\" : cannot get ACME client ACME challenge not specified, please select TLS or HTTP or DNS Challenge"

此消息在每个域中发布，内部和外部都是如此。找不到有关此问题的详细信息。

Traefik配置：

defaultEntryPoints = ["http", "https"]
idleTimeout = 0
dialTimeout = 0
logLevel = "WARN"

[entryPoints]

[entryPoints.http]
address = ":80"

#entryPoint = "https"

[entryPoints.https]
address = ":443"
[entryPoints.https.tls]

# Lets Encrypt via ACME
[acme]
email = "my@email.de"
storage = "acme.json"
entryPoint = "https"
onDemand = false
OnHostRule = true
caServer = "https://acme-v02.api.letsencrypt.org/directory"

[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "nas.one"
watch = true

您的traefik.toml文件尚未指定用于从Let's Encrypt获取证书的质询方法。关于这一点，1.7版本的错误消息更加清晰。

如果要使用HTTP challenge，请添加以下行：

[acme.httpChallenge]
  entryPoint = "http"

如果要使用DNS challenge (如果要使用通配符证书，则为必填项)，请添加以下行：

[acme.dnsChallenge]
  provider = "YOURPROVIDER"
  delayBeforeCheck = 0

有关其余配置，请查看文档。
