Bind9 为自定义区域返回 SERVFAIL

我正在尝试使用 Bind 为我的域设置 DNS 服务器。google.com对于非自定义域，如or ，服务器行为正确github.com，但对于我的域，它总是返回“SERVFAIL”。我已经检查了使用named-checkzone返回“OK”的区域文件。

我的区域配置（在 中定义named.conf.local）：

zone "michlfranken" {
  type master;
  file "/var/cache/bind/db.isiko404.dev";
};

我的选项文件：

options {
        directory "/var/cache/bind";

        // If there is a firewall between you and nameservers you want
        // to talk to, you may need to fix the firewall to allow multiple
        // ports to talk.  See http://www.kb.cert.org/vuls/id/800113

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.

        forwarders {
                80.241.218.68;
                46.182.19.48;
        };

        //========================================================================
        // If BIND logs error messages about the root key being expired,
        // you will need to update your keys.  See https://www.isc.org/bind-keys
        //========================================================================
