几次后sock.recv超时

Question

这是我连接服务器的功能（在我的情况下，是Samsung Smart TV，它是一个远程应用程序），然后该功能正在观看是否通过sock.recv（）连接到TV ok：

def connection(self):

        sock.connect((self.entry_tvip.get(), 55000))
        sock.send(part1)
        sock.send(part2)
        sock.settimeout(1)

        self.tvappstring = app.entry_tvappstring.get()
        self.connection_status()


    def connection_status(self):

        if sock.recv(1024) == "":

            print("Status: Disconnected")
            self.label_connection_status['text'] = 'Status: Disconnected'
            self.label_connection_status['fg'] = 'red'
        else:

            print("Status: Connected")
            self.label_connection_status['text'] = 'Status: Connected'
            self.label_connection_status['fg'] = 'green'

        self.master.after(random.randint(1000, 3000), self.connection_status)

但几次之后它就把这个错误输给了我，它停止了工作：

Status: Connected #The apps print
Status: Connected #The apps print
