我正在使用 pihole 转发绑定为本地 dns 服务。
[root@server ~]# cat /etc/redhat-release
CentOS Stream release 8
[root@server ~]# named -v
BIND 9.11.36-RedHat-9.11.36-13.el8 (Extended Support Version) <id:68dbd5b>
过去一切都很好。几周（或更长时间）我遇到了问题。今天我尝试解决login.live.com
我的 Windows PC（通过 pihole）：
PS C:\Users\xxx> nslookup.exe login.live.com
Server: pi.hole
Address: 192.168.120.10
*** Keine internal type for both IPv4 and IPv6 Addresses (A+AAAA)-Einträge für login.live.com verfügbar.
我的 Windows PC 通过绑定：
> login.live.com
Server: server.home.xxxxxx.de
Address: 192.168.2.20
*** login.live.com wurde von server.home.xxxxxx.de nicht gefunden: Unspecified error.
在皮孔上
pi@timeserver:~ $ nslookup login.live.com
;; Truncated, retrying in TCP mode.
;; Connection to 192.168.2.20#53(192.168.2.20) for login.live.com failed: host unreachable.
在绑定服务器上：
[root@server ~]# nslookup login.live.com
;; Truncated, retrying in TCP mode.
Server: 192.168.2.20
Address: 192.168.2.20#53
Non-authoritative answer:
login.live.com canonical name = login.msa.msidentity.com.
login.msa.msidentity.com canonical name = www.tm.lg.prod.aadmsa.akadns.net.
www.tm.lg.prod.aadmsa.akadns.net canonical name = prdv4a.aadg.msidentity.com.
prdv4a.aadg.msidentity.com canonical name = www.tm.v4.a.prd.aadg.akadns.net.
Name: www.tm.v4.a.prd.aadg.akadns.net
Address: 20.190.160.14
Name: www.tm.v4.a.prd.aadg.akadns.net

我完全不知道出了什么问题？为什么bind可以解析login.live.com，但客户端询问时不回答？
任何帮助将不胜感激
