How to connect ArduinoWebSockets to nodejs socket.io server deployed in fly.io?

Basically, I have an ESP8266 NodeMcu that connects to a wifi network. An RFID reader is connected and whenever the RFID card is tapped on the reader, an instance of SocketIoClient from ArduinoWebSockets will send an event on the server. I manage to make it work in Node.js Socket.io server deployed in Heroku, but I cannot connect it to my server deployed to Fly.io.

This is my code in my .ino file.

const char *server = "sbca-server.fly.dev";

inside the setup

webSocket.begin(server, 8080);

I am thinking that the problem here is the port of the server in fly.io.

because it works in Heroku using port 80 but did not work in fly.io.

const char *server = "sbca-server.herokuapp.com";
setup(){
    webSocket.begin(server, 80);
}

What is the correct port to use?

what is the question? it looks like you ask why it doesn't work if you connect to a different port? – Juraj Sep 25 '22 at 05:11
Thanks, I have to clear my question out. What is the correct port to be used for fly.io server? – Eric Echemane Sep 25 '22 at 05:33
I guess it is configurable, but the default HTTP port is 80 – Juraj Sep 25 '22 at 05:37
I've tried all the ports based on fly.io docs, 8080, 80 and 443. All of them did not work. – Eric Echemane Sep 25 '22 at 07:32
Sorry, I don't your question. `fly.toml` contains the port mapping. Maybe post this? – Marcel Stör Sep 26 '22 at 05:39
https://github.com/EricEchemane/sbca-server/blob/main/fly.toml this is my fly.toml file from the server repo – Eric Echemane Sep 26 '22 at 12:26
But this repo doesn't start any WebSocket servers… How is it supposed to work? – madhead Sep 29 '22 at 22:34
