python服务端Android客户端TCP .ErrnoException: connect failed: ETIMEDOUT

Question

求各位大佬帮帮我，16号就要完成的orz……
服务端
import sockettcpServerSocket=socket.socket()#创建socket对象
host = socket.gethostname()#获取本地主机名
port=12567#设置端口
tcpServerSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)#让端口可以复用
tcpServerSocket.bind((host,port))#将地址与套接字绑定，且套接字要求是从未被绑定过的
tcpServerSocket.listen(5)#代办事件中排队等待connect的最大数目
#tcpServerSocket.settimeout(10000)
while True:
    print("等待连接")
    #建立客户端连接,接受connection，返回两个参数，c是该connection上可以发送和接收数据的新套接字对象
    #addr是与connection另一端的套接字绑定的地址
    clientSocket, addr = tcpServerSocket.accept()    
    #clientSocket.settimeout(10000)
    print ('连接地址：', addr)
    while True:
        data=clientSocket.recv(4096)
        if not data:
            break
        #向客户端表示接收到数据
        str='来自服务端的消息！'
        clientSocket.send(str.encode())#字符串编码为字节
    #套接字在垃圾收集garbage-collected时会自动close
    #close关闭该connection上的资源但不一定马上断开connection
    #想要立即断开connection，要先调用shutdown再close
        clientSocket.close() # 关闭连接
tcpServerSocket.close()

Answer 1

我权限也有加了<uses-permission android:name="android.permission.INTERNET"/>
还有一个问题是：我的电脑有安装虚拟机，python服务端打印出来的套接字地址是用VMware Network Adapter VMnet1的IPv4地址
但是当我在android代码中如果把hostip改成无线网络连接的IPv4地址，日志就报错android.system.ErrnoException: connect failed: ECONNREFUSED，同样在36行，我该用哪个IP地址？我该怎么修改呢？
