CNAME规则将子域重定向到外部站点不起作用

Question

我在myDomain.com上托管我的个人网站，这是一个装有apache的Flask应用程序。我正在使用静态网站生成器和netlify创建一个个人博客，我希望将其托管在blog.myDomain.com

我已经在myDomain的DNS提供程序上为blog设置了CNAME规则，该规则指向netlify URL customNetlifyDomain.netlify.com，但这似乎不起作用。 curl -v blog.myDomain.com返回

* Connected to blog.myDomain.com (ipv6.addr) port 80 (#0)
> GET / HTTP/1.1
> Host: blog.myDomain.com
> User-Agent: curl/7.47.0
> Accept: */*
> 
< HTTP/1.1 404 Not Found

* Connection #0 to host blog.myDomain.com left intact
Not Found

我能够ping blog.myDomain.com并获得

 ping blog.myDomain.com
PING customNetlifyDomain.netlify.com (ip.addr) 56(84) bytes of data.
64 bytes from 142.93.108.123: icmp_seq=1 ttl=57 time=25.2 ms
64 bytes from 142.93.108.123: icmp_seq=2 ttl=57 time=34.7 ms
2 packets transmitted, 2 received, 0% packet loss, time 1001ms

还有nslookup blog.myDomain.com：

Server:     127.0.1.1
Address:    127.0.1.1#53

Non-authoritative answer:
blog.myDomain.com   canonical name = customNetlifyDomain.netlify.com.
Name:   customNetlifyDomain.netlify.com
Address: ip.addr

任何建议表示赞赏！

确保将子域别名添加到Netlify站点上的域管理中。
