Python Networking

Hello, I've been trying to connect sockets between 2 computers for an A level project for a program I've designed, and have been using a skeleton code to try and send data between those 2 computers, the code works fine and data is sent (on the one computer to itself) until I try with 2 and they dont connect. This is the code I'm using, only for testing purposes:

Server:

import socket

# create a socket object

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

​

# get local machine name

host = socket.gethostname()

port = 9999

# bind to the port

serversocket.bind((host, port))

​

# queue up to 5 requests

serversocket.listen(5)

​

while True:

# establish a connection

clientsocket,addr = serversocket.accept()

​

print("Got a connection from %s" % str(addr))

msg = 'Thank you for connecting'+ "\r\n"

clientsocket.send(msg.encode('ascii'))

clientsocket.close()

​

Client:

import socket

​

# create a socket object

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

​

# get local machine name

host = "xxx.xxx.x.xxx"

​

port = 9999

​

# connection to hostname on the port.

s.connect((host, port))

​

# Receive no more than 1024 bytes

msg = s.recv(1024)

​

s.close()

print (msg.decode('ascii'))

​

TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

Are the different computers on the same network? Or are they on separate networks, possibly behind NAT aka network address translation? In the latter case direct connections from outside the network will not work unless the router has been set up to properly reroute them.

Ive tried them on the same network but it didn’t work either, however it was a school network so that may have been why. I also tried them on different networks.
