attu 登录不上去（ cannot log in to Attu）

我使用docker-compose方式安装了milvus和attu,但是attu登录不上去，服务器是gpu服务器，同样的操作我之前在cpu服务器上是能登录的，配置文件也一样，两台服务器系统：cpu的是基于centos优化的阿里云系统，gpu的是centos7.6。点击attu connect按钮后具体的日志报错如下（I installed Milvus and Attu using docker-compose, but I cannot log in to Attu. The server is a GPU server. I was able to log in using the same setup on a CPU server with the same configuration file. The two servers have different operating systems: the CPU server is based on an optimized version of CentOS on Alibaba Cloud, while the GPU server is CentOS 7.6. When I click the "Connect" button in Attu, the specific error message in the log is as follows:）：

解决了，是因为我使用的公网IP访问，服务器需要开通8000端口访问19530端口的白名单
