Python Socket连接同一网络上的两个设备

Question

I am attempting to connect a simple server and client from two computers on the same network. Both the client and server cannot 'find' each other, as they do not move past .connect() and .accept() respectively. What am I doing wrong?

(Windows 10)

Server:

import socket

HOST = socket.gethostname()    #Returns: "WASS104983"
#I have also tried socket.gethostbyname(socket.gethostname)), returning: "25.38.252.147"
PORT = 50007

sock = socket.socket()
sock.bind((HOST, PORT))
sock.listen(5)

print("Awaiting connection... ")

(clnt, addr) = sock.accept()

print("Client connected")
…

and Client:

import socket

HOST = "WASS104983"    #Or "25.38.252.147", depending on the servers setup
PORT = 50007

sock = socket.socket()

print("Attempting connection... ")

sock.connect((HOST, PORT))

print("Connected")
…

I have gotten this to work before so I am not sure why it's not now.

I know there are a few questions of this calibre, but none seem to cover my problem.

Also, a wifi extender should not interfere with local transmissions should it?

I have always seen servers setup as such:

import socket
import threading

bind_ip = '0.0.0.0'
bind_port = 9999

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind((bind_ip, bind_port))
server.listen(5)

print("[*] Listening on {}:{}".format(bind_ip, bind_port))


def handle_client(client_socket):
    request = client_socket.recv(1024)
    print('received: {}'.format(request))
    client_socket.send(b'ACK!')
    client_socket.close()


while True:
    client, addr = server.accept()
    print("[*] Accepted connection from: {}:{}".format(addr[0], addr[1]))
    client_handler = threading.Thread(target=handle_client, args=(client,))
    client_handler.start()*

Where I think an important distinction from your post may be that the server accepting connections is within an infinite loop. Have you tried this?
