图一是反代配置，图二是报错。
为什么不解析frpc这级域名，而是解析g470呢？
实际我并没有设置g470这级的域名映射：
服务内部错误: stderr: 2024/12/06 16:09:27 [emerg] 402#402: host not found in upstream “g470.example.xyz” in /www/sites/g470.example.xyz/proxy/root.conf:2 nginx: [emerg] host not found in upstream “g470.example.xyz” in /www/sites/g470.example.xyz/proxy/root.conf:2 nginx: configuration file /usr/local/openresty/nginx/conf/nginx.conf test failed
