how to connect to external_ip in python socket programming

client.py

client_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

port = 443
socket_address = (<external_ip/global ip address>,port)
print("Socket Created")

# connect to server
client_socket.connect(socket_address)
print("Socket Connected")

server.py

server_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
host_name  = socket.gethostname()
host_ip = socket.gethostbyname(host_name)
print('HOST IP:',host_ip)
port = 443
socket_address = (host_ip,port)

# Socket Bind
server_socket.bind(socket_address)

# Socket Listen
server_socket.listen(5)
print("LISTENING AT:",socket_address)
server_socket.bind(socket_address

while True:
    client_socket,addr = server_socket.accept()
    print('GOT CONNECTION FROM:',addr)
    if client_socket:
        vid = cv2.VideoCapture(1)
        
        while(vid.isOpened()):
            img,frame = vid.read()
            frame = imutils.resize(frame,width=320)
            a = pickle.dumps(frame)
            message = struct.pack("Q",len(a))+a
            client_socket.sendall(message)
            
            cv2.imshow('TRANSMITTING VIDEO',frame)
            if cv2.waitKey(1) == '13':
                client_socket.close()

I am trying to connect to an external IP over a different network but the program takes to long to connect or it refuses to connect. how do I fix this...any suggestions please!
