Traefik无法获得ACME证书

Question

我想在服务器中的我的差异网站上使用treafik，但是我在使用Web服务器nginx重新安装Traefik时遇到问题。首次启动nginx容器时，不会生成证书。

错误：

time="2018-10-20T11:51:15Z" level=error msg="Unable to obtain ACME certificate for domains \"www.minenewgeneration.fr\" detected thanks to rule \"Host:www.minenewgeneration.fr\" : cannot get ACME client get directory at 'https://acme-v02.api.letsencrypt.org/directory': failed to get json \"https://acme-v02.api.letsencrypt.org/directory\": Get https://acme-v02.api.letsencrypt.org/directory: dial tcp 104.123.22.170:443: i/o timeout"

traefik.toml：
