Python 使用IP和端口检查服务器是否正常运行

您好，我创建了我的服务器-客户机模型，工作正常。现在我正在尝试创建一个seprate GUI，它接受两个输入

服务器ip

和

服务器端口

，然后它检查服务器是否启动或关闭，但当我尝试将GUI与服务器连接时，它会抛出此错误

文件“/root/PycharmProjects/usb monitor/server/server.py”，第20行，在客户端threadconn.send（'Hi'.encode（））#send只接受字符串断开管道错误：[Errno 32]断开管道

但在gui上，它显示

ip已启动

，但它在服务器端抛出上述错误。我相信这是我的

GUI

code中服务器的套接字连接问题

这是我的gui代码
