Trouble connecting to local nodejs WebSocket server

Question

I am trying to connect my game to a local Node.js websocket server I am running on the same machine. I have verified that my nodejs ws server is working correctly, as I am able to connect to it with an angular web server. My end goal is to create a game similar to the Jackbox games in terms of architecture.

However, when the sever is running and I try to connect my godot game client to the server, it hangs forever on “connecting”. meaning the GetReadyState() function of the WebSocketPeer object is hanging on the connection state. I get no connection logs from my nodejs server that it connected either.

Here is my nodejs server script:

const express = require('express');
const http = require('http');
const socketIo = require('socket.io');

const app = express();
const PORT = process.env.PORT || 3000;

const server = http.createServer(app);

const io = socketIo(server, {
    cors: {
        origin: "*",
        methods: ["GET", "POST", "WS"]
    }
})

io.on('connection', (socket) => {
    console.log("CLIENT CONNECTED");

    socket.on('message', (message) => {
        console.log(`Received message from client ${socket}: ${message}`);
        io.emit('message', message);
    })

    socket.on('disconnect', () => {
        console.log('CLIENT DISCONNECTED');
    })
})

server.listen(PORT, '192.168.0.28', () => {
    console.log("SERVER IS RUNNING ON http://192.168.0.28:3000");
})

And here is my c# script attached to a node object in an empty scene in godot:

using Godot;
using System;

public partial class WebsocketTest : Node3D
{
	const string url = "ws://192.168.0.28:3000/";

	WebSocketPeer webSocketPeer = new WebSocketPeer();

	public override void _Ready()
	{
		Error error = webSocketPeer.ConnectToUrl(url);
		if (error != Error.Ok)
		{
			GD.Print("Unable to connect to websocket server at " + url);
			SetProcess(false);
		}
		else
		{
			GD.Print("Connected to server at " + url);
		}
	}

	public override void _Process(double delta)
	{
		webSocketPeer.Poll();
		GD.Print(webSocketPeer.GetReadyState());
	}
}

The ready state of the websocket connection in Godot is always connecting:
