Web Socket Wan't Connect

So i have basic websock server running in a simple node.js project, but in production i says it can't connect. I have wss://mydomain:<port>/ and added my custom domain. But still it wan't let me do it. I will provide the basic websocket server below. It works fine on my local computer.

const wsServer = new ws.Server({ port: 8080 });

wsServer.on("listening", () => {
  Logger.debug("Websocket server is listening on port 8080");
});

wsServer.on("connection", (socket) => {
  Logger.debug("New websocket connection", socket);

  socket.on("close", () => {
    Logger.debug("Websocket connection closed");
  });
});

const wsServer = new ws.Server({ port: 8080 });

wsServer.on("listening", () => {
  Logger.debug("Websocket server is listening on port 8080");
});

wsServer.on("connection", (socket) => {
  Logger.debug("New websocket connection", socket);

  socket.on("close", () => {
    Logger.debug("Websocket connection closed");
  });
});

You should listen on the port railway provides to you ( env.PORT )

lasse•9mo ago

alright so const wsServer = new ws.Server({ port: process.env.PORT});

Alright let me test it out

Fragly•9mo ago

i'd recommend doing this though

const port = process.env.PORT || 3000
console.log(`Running on port ${port}`)

const port = process.env.PORT || 3000
console.log(`Running on port ${port}`)

that way if no PORT is defined it defaults to 3000 or whatever

what language does the syntax for env.PORT come from??

Fragly•9mo ago

I made it up <:chad_moment:758939193967378442>

thats confusing

PORT service variable*** weariest

Brody•9mo ago

PORT environment variable variables set in the service are service variables, during build they are called build arguments, during runtime they are environment variables

Fragly•9mo ago

That is good to know, thank you brody

Brody•9mo ago

(unless you set a PORT service variable yourself, the PORT variable generated by railway is only available at runtime as an environment variable)

lasse•9mo ago

It's still wan't connect

lasse•9mo ago

WebSocket connection to 'wss://websocket.orabot.xyz:8080/' failed and i have set my domain:

Fragly•9mo ago

remove the port specification at the end of the url you're not listening on that port

lasse•9mo ago

Thanks, let me test it It works now, thank you!
