无法连接，日志如下： box.log 尝试修改入站设置，将该部分修改为：

        //     "tag": "tun-in",

        //     "auto_route": true,
        //     "strict_route": true,
        //     "stack": "system",
        //     "sniff": false
        // }
        {
            "type": "socks",
            "tag": "socks-in",
            "listen": "::",
            "listen_port": 10808
        },
        {
            "type": "http",
            "tag": "http-in",
            "listen": "::",
            "listen_port": 10809,
            "set_system_proxy": false
        }
    ],

将系统代理设置为127.0.0.1:10809，可以正常访问网页。
