Python socket server port forwarding with ngrok

I am making a cli-chat system with python, sockets. When the server and client are in the same machine, the code works fine.

But now I am trying to port forward my local server with ngrok, to chat with remote clients.

When the client wants to connect he would have to give the server url. If I am giving my localhost url, client connects to the socket server and everything works fine.

But whenever I am giving the ngrok's tcp tunnel url, it doesn't works and throws the error below

Traceback (most recent call last):
  File "/storage/emulated/0/Sun/Python/cmd-chat/user.py", line 5, in <module>
    client.connect((serverUrl, 5000))              #connecting client to server
socket.gaierror: [Errno 7] No address associated with hostname

The url I am giving as input is, tcp://x.tcp.ngrok.io:17xxx

Solution

  • Hey I think I got where you are going wrong 

    # Your Server Url should be
serverUrl = hostAddress = "x.tcp.ngrok.io"

# The Port in which we want to connect to the server Should be
port = 17234 # The number given in the end of URL link
