Failed to access server socket via internet python3

Question

Good afternoon, I have a problem, I need to access there my pi Raspberry through a socket but when I test locally the program works perfectly, but when I try to access it through the internet (having installed in Raspberry pi a dynamic dns so it is always available), but I can not contact the server through the socket, I can access it through the browser but I need for my application that I can access it from the socket.

the server code is like this :

import socket
import threading
bind_ip="127.0.0.1"
bind_port=80
server = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
server.bind((bind_ip,bind_port))
server.listen(1000)
def handle_client(client_socket):
    request=client_socket.recv(1024)
    print("[*]Recevid: ",request.decode('utf-8'))
    client_socket.send("teste".encode)
    client_socket.close()

while True:
    client,addr=server.accept()
    print("[*]Accepted connection from: ",addr[0]," ",addr[1])
    client_handler=threading.Thread(target=handle_client(client))
    client_handler.start()

I even tried to replace the 127.0.0.1 for 192.168.1.3 or even by the service of ddns in these attempts I only got the error that could not use that as ip server if someone can help me thank

If you can with the browser, then probably the problem is in the client and not in your server. I hope I’ve helped.
