我今天才发现.app域名需要SSL证书。我购买它是为了DNS重定向到已经具有SSL证书设置的站点，所以我的问题是是否可以进行设置？

我正在使用Google Domains，将综合临时重定向设置为我的域名时出现错误。

This synthetic record has an error and will not function correctly:
The SSL Certificate for this domain hasn't been created yet. This process may take up to 24 hours to complete.
The required link to "https://my-existing-site.com" is not present.
An SSL certificate is missing.

有什么想法吗？
