Question

我试图通过Docker设置Cryptpad，可通过Traefik在公共服务器上访问。我有Traefik设置和Cryptpad，但到目前为止，导航到http://cryptpad.myserver.com（重定向到https，具体配置）我在浏览器中出现Bad Gateway错误，并在treafik容器中出现以下错误＆＃39 ; s日志：

level=warning msg="Error forwarding to https://172.19.0.2:3000, err: EOF"

此外，另一个可能相关的问题是，似乎我们的加密不能为cryptpad.myserver.com和monitor.myserver.com颁发证书（我根据说明配置了证书）这里https://www.digitalocean.com/community/tutorials/how-to-use-traefik-as-a-reverse-proxy-for-docker-containers-on-ubuntu-16-04）。

编辑： Bad Gateway问题似乎源于无法创建有效的证书，因为我可以通过Traefik通过普通HTTP达到Cryptpad（当然，在关闭相关的HTTPS配置之后）。这个问题的标题已经相应编辑，以反映这种关系。

例如，在尝试访问https://monitor.myserver.com时，我在traefik容器的日志中收到以下错误：

time="2018-01-10T13:53:37Z" level=info msg="Server configuration reloaded on :9080"

同样，当尝试访问http://cryptpad.myserver.com时，会记录以下ssl错误（以上面提到的EOF / Bad Gatewway错误结束）：

以下是Traefik及其docker-compose.yml文件的traefik.toml文件（均通过查阅上文[通过数字海洋]和Traefik自己在此处{{3}提到的指南进行配置}）：

以下是Cryptpad的.env和docker-compose.yml文件，我根据https://docs.traefik.io/user-guide/docker-and-lets-encrypt/和前面提到的指南收到并编辑了这些文件：

VERSION=latest
USE_SSL=true
STORAGE='./storage/file'
LOG_TO_STDOUT=true

搬运工-compose.yml

version: '2'
services:

  cryptpad:
    build:

      args:

    hostname: cryptpad

    labels:
      - "traefik.backend=cryptpad"
      - "traefik.docker.network=proxy"

      - default
    expose:

非常感谢任何帮助。＆安培;当然，如果有必要，我可以提供更多细节。

我认为你遇到了这个问题：

https://community.letsencrypt.org/t/solution-client-with-the-currently-selected-authenticator-does-not-support-any-combination-of-challenges-that-will-satisfy-the-ca/49983

由于安全问题，显然letsencrypt已禁用TLS-SNI-01。以下是该问题的链接：https://community.letsencrypt.org/t/2018-01-09-issue-with-tls-sni-01-and-shared-hosting-infrastructure/49996

看起来letsencrypt需要几天时间才能再次启用它。

Traefik错误转发EOF / Bad Gateway（让我们加密相关）
