I know this is a very common problem, but I can’t seem to find the solution to it, and I’m new to Node JS and Nginx.
I’m trying to run my Node JS app on port 80 of my site at example.com using a nginx reverse proxy, where my app is running on port 5000. I’ve searched countless forums and followed many tutorials step by step but when I run the app and go to http://example.com, it just doesn’t show the app, and shows the default page when there is no index.html file (I removed the index file just in case it was creating some kind of interference).
Just in case this matters, I am hosting 2 other domains on the same server.
Other Information:
- Server OS: Ubuntu, running VestaCP with File Manager
- Location of the Node App:
/home/admin/web/example.com/node-application
It works fine on port 5000, and I don’t get an error when I run the application listening on port 80.
Here’s a link to the Github Repository where all the code for the app is, but I’ll also add the server.js code here:
Server.js:
var express = require('express');
var http = require('http');
var path = require('path');
var socketIO = require('socket.io');
var app = express();
var server = http.Server(app);
var io = socketIO(server);
app.set('port', 5000);
app.use('/static', express.static(__dirname + '/static'));
// Routing
app.get('/', function(request, response) {
response.sendFile(path.join(__dirname, '/static/index.html'));
});
// Starts the server.
server.listen(5000, function() {
console.log('Starting server on port 5000');
});
var players = {};
io.on('connection', function(socket) {
socket.on('new player', function() {
players(socket.id) = {
x: 300,
y: 300
};
socket.emit("yoursocketid", socket.id);
});
socket.on('movement', function(data) {
var player = players(socket.id) || {};
if (data.left) {
player.x -=5;
}
if (data.up) {
player.y -= 5;
}
if (data.right) {
player.x += 5;
}
if (data.down) {
player.y += 5;
}
});
socket.on('disconnect', function() {
io.sockets.emit('player disconnected', "player " + socket.id + " disconnected");
delete players(socket.id);
});
socket.on("chat message", function(data) {
console.log("message from " + data.from + ": " + data.message);
io.sockets.emit("new message", data.from + ": " + data.message);
});
socket.on("myusername", function(data) {
players(socket.id).username = data;
});
});
setInterval(function() {
io.sockets.emit('state', players);
}, 1000 / 60);

I have also tried moving the server block that is in /etc/nginx/sites-enabled/default to /etc/nginx/conf.d/thealonegames.com.confbut it still didn’t work.
I also tried setcap, although I know it’s not as secure, but it still didn’t change anything.
Am I doing something wrong in the configuration, or is there something I forgot to do? Please let me know of anything that could be causing the problem, it would really help. Thank you!
