Code works on Ubuntu but not MAC

Hi All,

I am trying to write a client and server app.

Testing on 2 clients MAC 10.11.3 and Ubuntu 14.04.3 LTS.

When I run the client on the MAC in the PyCharm Community Edition 5.0.4 I do not get output on the server. The side seems to work fine but nothing is displayed on the server.

When I run the client from a shell prompt on Ubuntu I get output on the server.

Client program does not work on MAC, SFTP to Ubuntu and it works.

Server program running on Ubuntu 14.04.3 LTS.

Client.py

#!/usr/bin/python3

import socket

targetIP = "x.x.x.x" # actual IP Address in code - I do not get any socket errors
target_port = 9999

target = (targetIP, target_port)


def client():

    clnt = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    try:
        clnt.connect(target)
    except socket.error as e:
        print("Connect error ", e)
        exit(1)

    while True:

        try:
            msg = input("What do you want to send? ")
            msg = bytes(msg, 'utf8')
            clnt.send(msg, 2048)
        except socket.errno as e:
            print("Socket error ", e)

    clnt.close()

client()

Server.py

#!/usr/bin/python3

import socket

hostIP = "0.0.0.0"
hostport = 9999

hosts = (hostIP, hostport)

def Server():

   srvr = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   srvr.getsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR)
   srvr.bind(hosts)
   srvr.listen(5)


   clnt, addr = srvr.accept()

   while True:
      data = clnt.recv(2048)
      if not data:
         break
      else:
         print(data.decode("utf-8"))
   srvr.close()

Server()
