捕获套接字超时错误

我想抓住插座。超时错误,以下是我的代码:

import socket
import sys
from time import sleep

print("Server Listening...")
IPparse = "localhost"
Portparse = 4444
serverSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = (IPparse, Portparse)
serverSocket.settimeout(5)
serverSocket.bind(server_address)
serverSocket.listen(2)
(server, (ip,port)) = serverSocket.accept()
try:
    data = server.recv(16).decode()
    if data == "Hello":
        print("Hallo Bro")
except socket.timeout as e:
    print ("Timeout is over")
    print (e)

但当我运行代码时。我遇到了以下错误:

Server Listening...
Traceback (most recent call last):
  File "C:\Users\astend\Desktop\TA\20180220 - Gabungan Gui  - v.1\Socket\terima2.py", line 13, in <module>
    (server, (ip,port)) = serverSocket.accept()
  File "C:\Users\astend\AppData\Local\Programs\Python\Python36\lib\socket.py", line 205, in accept
    fd, addr = self._accept()
socket.timeout: timed out

我在这里遗漏了什么关键点?
