I am not getting the reply from the server that I want using Python.

I am starting to use FIX API, but I do not know C#, so I am tring to use Python. I have created a MessageConstructor that constructed the following message:

8=FIX.4.4|9=126|35=A|49=icmarkets.3327814|56=cServer|57=TRADE|50=BVN|34=1|52=20180326-18:06:43.105|98=0|108=30|141=Y|553=3327814|554=password|10=206|

When I try to send this message to the server, I get a NoneType message as reply. I do not know where the problem is. It can be the message, the way that I am using to connect to the server or anything else. This is the code that a I am using to communicate with the server:

import socket

class API_Socket:
    def __init__(self):
        self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    def connect(self, host, port):
        self.sock.connect((host, port))

    def send(self, msg):
        self.msg=msg
        self.sock.send(msg)

    def receive(self,buffer=1024):
        data=b''
        while True:
            part=self.sock.recv(buffer)
            data+=part
            if len(part)<buffer:
                break
        self.sock.close()
        data_semi_parsed=data.decode().replace('\u0001','|')
        return data_semi_parsed

    def get_reply(self,host,port,msg,buffer=1024):
        self.connect(host,port)
        self.send(msg)
        return self.receive(buffer)

if __name__=='__main__':
    message='8=FIX.4.4|9=126|35=A|49=icmarkets.3327814|56=cServer|57=TRADE|50=BVN|34=1|52=20180326-18:06:43.105|98=0|108=30|141=Y|553=3327814|554=password|10=206|'
    byte_message=bytearray(message.replace('|','\u0001'),'utf-8'))
    s=API_Socket()
    response=s.get_reply('h43.p.ctrader.com',5201,byte_message)
    print(response)

Any help or advise will be welcome.
