Is it possible to communicate using the vidstream library from different PCs and outside the local network?

Question

Python

It only works for me on one PC. Connecting from another PC does not work, both on the local network and on the other.

Server:

from vidstream import AudioSender
from vidstream import AudioReceiver
import threading
import socket

ip = socket.gethostbyname(socket.gethostname())
print(ip)

receiver = AudioReceiver(f'{ip}', 9999)
receive_thread = threading.Thread(target=receiver.start_server)
receive_thread.start()

while input("") != 'q':
    continue
receiver.stop_server()

Customer:

from vidstream import AudioSender
from vidstream import AudioReceiver
import keyboard
import threading
import socket

sender = AudioSender('ip cервера', 9999)


sender_thread = threading.Thread(target=sender.start_stream)

sender_thread.start()

def print_key_stop():
    sender.stop_stream()

keyboard.add_hotkey("0", lambda: print_key_stop())

github hints that most likely it is impossible.
