sing-box 在 iOS 中自定义的域名解析不了

op 想使用 sing-box 在 iOS 手机上创建 vpn 然后连接家中公网 ip 暴露的 vmess 端口，家中的路由器自定义了一些域名，但是在 iOS 手机上访问域名无法打开家里面局域网的页面,直接使用 ip 访问却没问题，感觉应该是 DNS 解析出问题了。不过同样的配置（ inbox 修改了一下，iOS 上使用 tun ，PC 上使用 http ）在 PC 上测试了也是没题，希望有了解的 V 友帮我解答一下，下面是我 iOS 上的配置文件

{ "dns": { "servers": [ { "tag": "local", "address": "local", "detour": "direct" }, { "tag": "home-dns", "address": "192.168.0.1", "detour": "home" } ], "rules": [ { "domain_suffix": "app.home", "server": "home-dns" } ], "strategy": "ipv4_only" }, "inbounds": [ { "type": "http", "tag": "http-in", "listen_port": 53530 }, { "type": "tun", "tag": "tun-in", "interface_name": "tun0", "inet4_address": "172.19.0.1/30", "auto_route": true, "strict_route": true, "stack": "gvisor", "sniff": true } ], "outbounds": [ { "type": "direct", "tag": "direct-out" }, { "tag": "home", "type": "vmess", "server": "server", "server_port": 10000, "uuid": "uuid", "alter_id": 0, "network": "tcp" } ], "route": { "rules": [ { "ip_cidr": [ "192.168.0.0/16" ], "outbound": "home" }, { "domain_suffix": "app.home", "outbound": "home" } ], "final": "direct-out" } }
