ecs服务器上装了docker并安装了nginx能访问到，当我需要配置请求转发却无法访问

我的配置文件如下 worker_processes 1;

events { worker_connections 1024; }

http { include mime.types; default_type application/octet-stream;

sendfile        on;



keepalive_timeout  65;

xxxx服务都能访问，但这个监听到底是写内网还是公网，我都试过了但是通过外网无法访问

server {
    listen       6868;
    server_name  localhost;
    
     location ~ /edu/ {
         proxy_pass http://192.168.xxxx:8000;
     }
     location ~ /oss/ {
         proxy_pass http://192.168.xxxx:8001;
     }
	 location ~ /aliyun/ {
         proxy_pass http://192.168.xxxx:8002;
     }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

}
