Heroku ssl certficate未使用自定义域切换

Question

我有一个heroku应用程序（无论-app-11123），我想通过ssl（https://myapp.co）使用自定义域名。 我已经购买了证书，并按照heroku提供的所有说明进行操作。 奇怪的是，https://whatever-app-11123显示myapp.co证书，https://myapp.co显示* .herokuapp.com证书。

我需要将此作为另一种方式：myapp.co with myapp.co certificat。

有关如何实现这一目标的任何提示？

不同命令的结果：

herok：证书

Answer 1

以下是答案：检查您的DNS重定向。确保它是一个CNAME类型和最重要的（我做错了）重定向应该是：

www.myapp.co -> whatever-app-11123.herokuapp.com 
myapp.co -> whatever-app-11123.herokuapp.com

而不是

www.myapp.co -> myapp.co
myapp.co -> whatever-app-11123.herokuapp.com
