Client Socket not getting connect MQL5 with Python Server

Question

The following is the scenario of me trying to connect the socket through MQL5 as client, but the server is from the Python. See the following:
Server.py

import socket

def actual_work():

    return 'dummy_reply'


def main():
    sock = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
    try:
        sock.bind( ('127.0.0.1', 6666) )

        while True:
            data, addr = sock.recvfrom( 4096 )
            reply = actual_work()
            sock.sendto(reply, addr)
    except KeyboardInterrupt:
        pass
    finally:
        sock.close()
if __name__ == '__main__':
    main()

Client from MQL5

#include <simple-client-socket-send-only.mqh>

ClientSocket * glbSocket;

void OnInit()
{
   glbSocket = new ClientSocket("127.0.0.1", 6666);
   if (!glbSocket.IsSocketConnected()) {
      Print("Failed to connect");
   }
}

void OnDeinit(const int reason)
{
   delete glbSocket;
}


void OnTick()
{
   if (glbSocket.IsSocketConnected()) {
      Print(glbSocket.Send("Hello"));
   }
}

The library included is here: Socket client MQH

I am not able to connect to the socket using this format. Please let me know, if I am missing something. Help me improve.
