Python help please :)

[jcole54321]

Hi , any help anyone could offer would be greatly appreciated, basically im trying to write a server which allows multipul clients to connect and send messages to the server. so far i have a login working and the server allows multipul connections. however when i call the "Chat() funtion it only seems to allow each user to send one message. Yet it allows one client to send loads of messages without crashing, the error i get is :

"ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine" 

ive looked online and it says the antivirus/firewall could be causing problems butt ive tried disabling both yet i still get the same problem.

 

to me it seems like a problem with either the function of the multithreading. Any help would be massivly appreciated and the code is included below. 

 

Thanks in advance

I believe the server is sending messages but they are not being received and so it waits before doing anything else.

To fix this you should probably be receiving the messages sent even if nothing is done with them.

 

def Chat():
    NickName = input("Please enter a nickname: ->")
    message=""
    while message!= NickName+",end":
        
        s.recv(128)
        message =NickName + ","+ str(input("Send: ->"))
        s.sendall(message.encode())

    s.close()
    input("\n\n press enter to close")
    print("successfully disconnected from the server")
