connection reffused

[LuLove]

Hello! I'm trying to create a client-server application. I have a question on luasocket. I connect the socket = require ("socket") library and write the code:

function Backgammon: rand ()
   host = "localhost"
   port = 28005
   c = assert (socket.connect (host, port))
   return c: receive ()
end

The interpreter returns an error: "connection reffused".

If I write like this:

function Backgammon: rand ()
   host = "localhost"
   port = 28005
   if arg then
     host = arg [1] or host
     port = arg [2] or port
   end
   c = assert (socket.connect (host, port))
   return c: receive ()
end

The interpreter returns an error: "host of service not provided, or not know"

How to connect?

Hi and welcome to the forums.

Have you tried "127.0.0.1" as the host?

Silly question: Are you at least running a server at this port? You only wrote the client part, which connects to a server. If no server is running on the port of your desire then the connection will be refused

I'm sorry. Indeed, I was just trying to connect through different ports between them
