客服连接失败

按照文档说明里，启动了workerman.bat，

在小皮里也配置了nginx

 location / { 
   if (!-e $request_filename) {
   rewrite  ^(.*)$  /index.php?s=/$1  last;
   break;
    }
 }

 location /notice {
        proxy_pass http://127.0.0.1:50002/;  
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header X-real-ip $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
    }
    location /msg {
        proxy_pass http://127.0.0.1:50003/;  
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header X-real-ip $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
    }

可是依旧是客服连接失败，这个问题是我哪里没有配置对吗
