此问题的原因是从注册商的 DNS 服务器切换到 Google Cloud DNS 时 DNS 配置错误。目前没有您的域seebelarus.by 的 NS 记录:

要解决您的问题并切换到 Google Cloud DNS,您应该按照以下步骤操作:
-
转到 registrar's domain control panel 并为您的域设置新的 DNS 服务器,您应该替换您的域:
ns1.domain.by
ns2.domain.by
与:
ns-cloud-b1-googledomains.com
ns-cloud-b2-googledomains.com
ns-cloud-b3-googledomains.com
ns-cloud-b4-googledomains.com
-
转到 Google Cloud DNS 并从区域中删除 NS 记录:
ns1.domain.by
ns2.domain.by
你不再需要它们了,应该只有与 Google NS 相关的记录:
ns-cloud-b1-googledomains.com
ns-cloud-b2-googledomains.com
ns-cloud-b3-googledomains.com
ns-cloud-b4-googledomains.com
保持A 记录不变,现在是为www.seebelarus.by 添加CNAME 记录的好时机。
您可以在文档Cloud DNS Quickstart 中找到更多详细信息。
之后,您应该等待 24-48 小时才能收到 DNS propagation。您可以使用dnsmap.io、https://dnschecker.org/ 或类似工具等在线工具检查您的域的 DNS 传播状态。
更新
DNS 配置现在看起来不错:
