github pages外部域名问题

Question

域名解析到github pages后，每次发文章，都会收到github的邮件，如下：

The page build completed successfully, but returned the following warning for the master branch:
Your site's DNS settings are using a custom subdomain, www.xxx.xxx, that's set up as an A record. We recommend you change this to a CNAME record pointing at <username>.github.io. For more information, see https://help.github.com/artic...

明明已经解析成功了啊，CNAME文件也写了，都能正常访问了，这个要怎么解决？？

Answer 1

正确解析是使用CNAME将你的域名解析到 xx.github. io 。
不要使用A记录解析到ip。

Answer 2

给你看一下我的解析设置
