TCP Socket not connecting [WinError 10060] - Python

I'm making a chat app using sockets in python, but when I try to connect from a different computer then it says:
C:\Users\James\OneDrive\Documents\Python\Projects\Gui Chat\client.pyw
[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
This is the server code for the socket:
host = socket.gethostbyname(hostname)
port = 55555
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind((host, port))
print(f"IP: {server.getsockname()[0]}\nPORT: {server.getsockname()[1]}")
server.listen()
I also have a while True loop accepting all requests:
while True:
client, address = server.accept()
print(f"Connected with {str(address)}")
On the client end this is the socket code:
IP = simpledialog.askstring("IP", "Enter IP address", parent=root) # "192.168.1.252" # input("Enter IP: ")
nickname = simpledialog.askstring("Nickname", "Choose a nickname", parent=root)
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
client.connect((IP, 55555))
except Exception as e:
print(e)
The programme asks for the IP address each time, and when I put in the correct IP for the server computer, it comes up with the error above. It works if I try to connect from the same computer, and they are both on the same network. It was working recently, and now it has just stopped working.
UPDATE:
I have set the server ip to 0.0.0.0, I have set up a port forwarding rule, I have checked the firewall and allowed incoming and outgoing connections, and I have run nmap with these results:

Code issues
First try binding server on localhost or 127.0.0.1.
FireWall/Ports issues
Check if your computer's default computer/antivurus
firewall (where server is hosted) allow connections
on your port 55555.
And if computer with client is outside your home network
point to router public IP address and make sure you have
port forwarding setup on router.
Address issues
Are you sure that IP you are writing in client is correct.
Go to your computer with server and check that IP.
Windows:
Go to cmd or Power Shell and type ipconfig, then find
section IPv4 Address and look that address you habe there.
Linux / MacOS
Go to your terminal and type ifconfig -a, and
it should be somewhere there, but I don't have those systems,
so I can't test it for you. If it does't work try to search how to
find that out.

Python & Mcpi (minecraft) - connection refused error

I use mcpi: https://github.com/AdventuresInMinecraft/AdventuresInMinecraft-Linux
Starting the local server.
After, run program:
import mcpi.minecraft as minecraft
mc = minecraft.Minecraft.create()
mc.postToChat("Hello Minecraft World")
I am facing the below error:
Traceback (most recent call last):
File "/home/home/AdventuresInMinecraft/MyAdventures/HelloMinecraftWorld.py", line 2, in mc = minecraft.Minecraft.create()
File "/home/home/.local/lib/python3.6/site-packages/mcpi/minecraft.py", line 376, in create return Minecraft(Connection(address, port))
File "/home/home/.local/lib/python3.6/site-packages/mcpi/connection.py", line 17, in init self.socket.connect((address, port))
ConnectionRefusedError: [Errno 111] Connection refused

A ConnectionRefusedError means that the address + port combination was unable to be secured for this particular Minecraft server and thus raised an exception. This could be because some other application is already using the port of interest, the port is unavailable because of the OS, or a handful of other networking configuration mishaps.
But perhaps a better series of questions to ask yourself is:
What is the default address and port that minecraft.Minecraft.create() will attempt to launch / listen at?
Do I have access to that server (address + port)?
If I do have access, are there any security issues (AKA Firewall)?
This post has already addressed the root issue of your question, and I hope it gives you a good start at understanding the foundation of your problem.
Notice how their question mentions s.connect((host,port)) and your stack trace has self.socket.connect((address, port)) Looks like the same thing to me!
Some more reading:
- localhost
- check if port is in use

I encountered the same issue. I looked into the code of mcpi and found that the default port is 4711. However, a Minecraft Server's default port is 25565. All you need to do is add 2 parameters on the create() function. Code(Python):
mc = minecraft.Minecraft.create(address="127.0.0.1", port=25565)
btw change "address" in the code to the host of the server (only if you modified the "server.properties" file).
Also, ConnectionRefusedError doesn't mean that it's not secured, I believe it means that either the server is not online, it doesn't exist, or the server refused it for some reason.
EDIT:
Oops sorry I just found out that mcpi actually connects to the RaspberryJam plugin which is hosted on another IP and port. The plugin runs on port 4711. So mcpi has the right port.
So check if you have the RaspberryJam plugin installed. If not, download it from
https://www.spigotmc.org/resources/raspberryjuice.22724/
And put the .jar file inside the plugins folder in your server directory.

Host command and ifconfig giving different ips

I am using server(server_name.corp.com) inside a corporate company. On the server i am running a flask server to listen on 0.0.0.0:5000.
servers are not exposed to outside world but accessible via vpns.
Now when i run host server_name.corp.com in the box i get some ip1(10.*.*.*)
When i run ifconfig in the box it gives me ip2(10.*.*.*).
Also if i run ping server_name.corp.com in same box i get ip2.
Also i can ssh into server with ip1 not ip2
I am able to access the flask server at ip1:5000 but not on ip2:5000.
I am not into networking so fully confused on why there are 2 different ips and why i can access ip1:5000 from browser not ip2:5000.
Also what is equivalent of host command in python ( how to get ip1 from python. I am using socktet.gethostbyname(server_name.corp.com) which gives me ip2)

As far as I can tell, you have some kind of routing configured that allows external connections to the server by hostname (or ip1), but it does not allow connection by ip2. And there is nothing unusual in this. Probably, the system administrator can advise why it is done just like this. Assuming that there are no assynchronous network routes, the following function can help to determine public ip of server:
import socket
def get_ip():
try:
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.connect(("8.8.8.8", 80))
local_address = sock.getsockname()
sock.close()
local_address = local_address[0]
except OSError:
local_address = socket.gethostbyname(socket.gethostname())
return local_address

Not quite clear about the network status by your statements, I can only tell that if you want to get ip1 by python, you could use standard lib subprocess, which usually be used to execute os command. (See subprocess.Popen)

library socket: open port

I have try to create a little online game with python but I face a problem.
I have no problem as long as I work in local (same computer or private IP adresse) but the socket can't connect if i use an IP.
Server:
import socket
co_prin = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
co_prin.bind(('', 9000))
co_prin.listen(10)
co,info=co_prin.accept()
print('connexion recu')
co.close()
co_prin.close()
Client:
import socket
co_serv=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
adresse='81.56.76.61'
co_serv.connect((adresse, 9000))
print("Connecté.")
co_serv.close()
If I change adresse by 'localhost' there is no problem.
One tell me that the reason was python can't open the port. I would like to know if there is a solution to solve or bypass the problem easy to use for other user. (I can always create a local network with hamachi or open the port manually but it's wouldn't be easy to share my programm).
Edit, the error in the client code: Traceback (most recent call last):
File "", line 5, in
co_serv.connect((adresse, 9000))
socket.error: [Errno 10061] No connection could be made because the target machine actively refused it

You are not using your actual computer IP. You are using your public IP address.
Open cmd/command.com and type in the command: ipconfig.
You will there see a totally different IP (IPv4/IPv6 address):
Most likely you want this (do this for yourself!):
Then, if you want people outside your network want to access your computer you must port forward the port to your network IP address from your router.
If you are just experimenting with python, it's best to use 127.0.0.1 or localhost as IP-address.

Raspberry PI Server/Client Socket in Python

I am trying to set up a Python socket between my Raspberry Pi (running Raspbian) and my Macbook Pro (running Mavericks).
Both devices are connected to the same WiFi network in my appt. I run the server code on my RPi and then the client code on my Macbook (I have also tried the reverse). I think that I am missing a set up step because the code I am using I found on multiple sites, so I assume it works. I also checked that my Macbook has firewall turned off.
Server Code:
from socket import *
host = "127.0.0.1"
print host
port = 7777
s = socket(AF_INET, SOCK_STREAM)
print "Socket Made"
s.bind((host,port))
print "Socket Bound"
s.listen(5)
print "Listening for connections..."
q,addr = s.accept()
data = raw_input("Enter data to be sent: ")
q.send(data)
Client Code:
from socket import *
host = "127.0.0.1"
print host
port=4446
s=socket(AF_INET, SOCK_STREAM)
print "socket made"
s.connect((host,port))
print "socket connected!!!"
msg=s.recv(1024)
print "Message from server : " + msg
I get the error:
Traceback (most recent call last):
File "TCPclient.py", line 9, in <module>
s.connect((host,port))
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py",
line 224, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 61] Connection refused
My process for executing the code is:
type "python TCPserver.py" into RPi terminal
type "python TCPclient.py into Macbook terminal
Then I receive the error message on my Macbook, no error on the RPi
My questions are:
Is 127.0.0.1 the proper input for "host"? (please note I also tried "localhost")
Does the input for host have to be the same for the client and server code?
Should the RPi and Macbook both be connected to the same WiFi network?
Is there any set up that needs to be done on either the RPi or my Macbook in order for this to work (Please note my RPi is Model B, new, and I did not set up anything else on it before this)
Do you know why I am receiving this error and how to fix it?
Your help is greatly appreciated!!

127.0.0.1 is a special IP address for local machine.
You must set the real IP address (on your LAN) of you mac in the client code.
You should also bind on this IP on the server, or on 0.0.0.0 to bind on all available IP addresses.
You must also use the same port number on both client and server.
And to reply to your questions:
Is 127.0.0.1 the proper input for "host"? (please note I also tried "localhost")
127.0.0.1 is the same than localhost, it means the local machine. This will work if you run the client and the server on the same machine, else you need the real IP address of your mac. Try ifconfig in a console.
Does the input for host have to be the same for the client and server code?
Yes and no. On the server you bind to a port and an address, so you'll wait for connections on this port and address. You can use the IP address, or 0.0.0.0.
Should the RPi and Macbook both be connected to the same WiFi network?
Yes and no. It will work with the same WiFi network, but it will also work with two different WiFi networks if they are connected together directly or with a IP router. Most of the time though they are connected to the internet through a NAT (network address translator), and then it will not work.
Is there any set up that needs to be done on either the RPi or my Macbook in order for this to work (Please note my RPi is Model B, new, and I did not set up anything else on it before this)
I don't know much about the RPi but it looks like standard TCP sockets, that should work out of the box.
Do you know why I am receiving this error and how to fix it?
As I stated at the beginning: You try to connect to the RPi (127.0.0.1) on the wrong port.

You have created a listener on port 7777, then you connected on 4446 !!!!!
just connect on the same port you are listening to =)
