Python socket networking problem with IP

Question

Hay friends I am beginner to python networking. And recently working on python socket module.
So my question is I had created 2 file
1st). Server.py
2nd). Clint.py
and you all know we need a ip to transfer data . I had used the dynamic local ip provided by ISP . Ok . It works fine when I connect my client smart phone with server smartphone through wifi then my interpreter of server ( using pydroid3 ) give the connection of Clint. But when I was trying to acces the same conectiction without wifi but I am using internet instead of wifi . Then I was fail to achieve the same connection. Now I am confused here because the code playground doesn't show any error. So my question is that what should I do . And I dont think that same connection can be done using public IP which Google tells you.
So how can I fix it . You can see the source code of clint and server below in answer section.

Point to noted : there is no problem with dynamic ip because I always update ip before trying connection.

‐‐‐> Server python code

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = '100.92.12.157' #this is ip
port = 1204
s.bind((host,port))
s.listen(1)
socketclint , address = s.accept()
print("got conection from :",address)
con = True
while con:
msg = socketclint.recv(1024)
msg = msg.decode("utf-8")
print("clint data :",msg)
ap = input("enter msg : ")
socketclint.send(ap.encode("utf-8"))
if msg == "quit":
s.close()
con = False

---> Clint python code

import socket
import os
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = '100.92.12.157' #this is ip
port = 1204
s.connect((host,port))
con=True
while con:
msg = input('enter msg : ')
s.send(msg.encode("utf-8"))
var=s.recv(1024)
var=var.decode('utf-8')
print('server data :',var)
if msg == 'quit':
con = False
s.close()

Then what else can I do Kuba Siekierzyński sir. I have a way to create a digital server over digital ocean but its paid . And I dont want paid service. Is their any other way also

Answer 3

Are you sure your ISP allows such access and there is no firewall in place? This might not be a problem when you are using your own router and access thru Wi-Fi, but outside your local network those two machines are using a connection rules of which may not allow such direct access...

Answer 4

its has been noted the code promts the re cycle on the run as executed as id as if no error .... found perhaps the bit tyracker is promting the same issue hence its has been taken on consideration...

What do you want to say Coder SUXROB :-)

Answer 7

port forwarding is the best option maybe your ports are closed

Answer 8

I think you should find out how a router works and routing is implemented. You have to configure a port forwarding in your router which should solve your problem.
