我尝试将Cloudflare提供的免费SSL服务应用于我的Heroku应用程序。
虽然我在4天前注册了我的域名，但它没有用。
当我尝试使用Chrome访问我的域（example.com和www.example.com）时，会显示This site can’t be reached example.com’s server DNS address could not be found.。
检查Cloudflare网站时会显示以下消息。
An A, AAAA or CNAME record was not found for the www subdomain. The www.example.com subdomain will not resolve.
An A, AAAA or CNAME record was not found pointing to the root domain. The example.com domain will not resolve.
An MX record was not found for your root domain. An MX record is required for mail to reach @example.com addresses.
在使用Cloudflare之前，我可以访问我的域www.example.com。
如何在SSL中使用我的域名？
我在Cloudflare中的设置摘要如下;
Security Level: Medium
SSL: Full
我获取了我的域名并在主页上设置如下，我获得了我的域名。
sub domain: www
type: CNAME
content: floating-fortress-999999.herokuapp.com
name server1: foo.ns.cloudflare.com
name server2: bar.ns.cloudflare.com
当我尝试dig命令时，会显示以下内容。
$ dig example.com
