正常使用浏览器可以访问并查看到三个节点均为up状态

但是通过代码注册显示如上报错信息，这是因为在2.0之后增加两个端口号

解决办法：

        1、关闭防火墙（不推荐）

        2、开放端口号

        3、还有一种情况为nginx代理需要增加如下配置

                注意：1、stream 需要和http同级别

                            2、upstream cluster中的端口号为nacos中配置的主端口号 1000得到的

代码语言：javascript复制
stream {
   include /usr/local/nginx/nginx-1.23.1/conf/vhost/stream/*.conf;
   upstream cluster{
            server 192.168.164.160:9848; // 主端口号偏移量   1000
            server 192.168.164.161:9848; // 主端口号偏移量   1000
            server 192.168.164.162:9848; // 主端口号偏移量   1000
    }
     
    server {
       listen 8888;  
       proxy_connect_timeout 1s; 
       proxy_timeout 3s; 
       proxy_pass cluster;     
    } 
}

项目中配置文件注册端口号如下
