当我试图通过python套接字连接到clickhouse服务器时，收到以下消息：

received data:  b'\x02e\x00\x00\x00\x10DB::NetException/DB::NetException: Unexpected packet from client\xf8\x070.

这是我的python代码

TCP_IP = "localhost"
TCP_PORT = 9000
BUFFER_SIZE = 1024
MESSAGE = "--user default --password xxxxxxx".encode("utf-8")
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
c = s.connect_ex((TCP_IP, TCP_PORT))
print (c)
s.send(MESSAGE)
data = s.recv(BUFFER_SIZE)
s.close()
print ("received data: ", data)

我认为这个错误来自发送到服务器的错误消息，但是当我在ubuntu终端输入相同的内容时，它没有错误。我该怎么修？
