        root /var/www/mydomain.com/html/AngularBee/dist;
        index index.html index.htm index.nginx-debian.html;

        server_name mydomain.com www.mydomain.com;

        location / {

                try_files $uri $uri/ /index.html;

                proxy_set_header 'Access-Control-Allow-Methods' 'GET,POST,OPTIONS,PUT,DELETE,PATCH';

                proxy_pass http://btb;
                proxy_http_version 1.1;

                proxy_set_header Connection 'upgrade';
                proxy_set_header Upgrade            $http_upgrade;

server {

    if ($host = www.mydomain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    if ($host = mydomain.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

        return 404; # managed by Certbot

Here is the entry point of my application:

'use strict';
      express     = require('express'),
      path        = require('path'),
      http        = require('http'),
      bodyParser  = require('body-parser'),
      mysql       = require('mysql'),
      dotenv      = require('dotenv').config(),
      cors        = require('cors');

module.exports = () => {
    let server = express(),

    create = (config) => {
       //Allow cors origin
        let routes = require('./routes/index');

        //Server settings
        server.set('env', config.env);
        server.set('port', config.port);
        server.set('hostname', config.hostname);

        //Middleware that parses json
        server.use(bodyParser.json({limit: '50mb', extended: true}));
        server.use(bodyParser.urlencoded({ limit:'50mb', extended: true}));

        // Point static path to dist

        // Catch all other routes and return the index file
        server.get('/', (req, res) => {
          res.sendFile("index.html", {"root": 'C:/dev/myproject/dist'});

      server.use(function(req, res, next) {
        res.header("Access-Control-Allow-Origin", "*");
        res.header("Access-Control-Allow-Methods", 'GET, PUT, PATCH, POST, DELETE');
        res.header("Access-Control-Allow-Headers", "Content-Type");

        //Set up routes by deferring that responsibility to the index.js within the routes folder.

        const connection = mysql.createConnection({
          host     :  config.hostname,
          user     :  config.user,
          password :  config.password

        connection.connect( (error) => {
            console.log('Error Connexion to database');
            console.log('Connected to Database');

    start = () => {
         let hostname = server.get('hostname'),
             port = server.get('port');

         server.listen(port, () => {
             console.log('Express server listening on - http://' + hostname + ':' + port);

      create: create,
      start: start

And finaly this is my error:

error: error { target: XMLHttpRequest, isTrusted: true, lengthComputable: false, … }
headers: Object { normalizedNames: Map(0), lazyUpdate: null, headers: Map(0) }
message: "Http failure response for (unknown url): 0 Unknown Error"
name: "HttpErrorResponse"
ok: false
status: 0
statusText: "Unknown Error"
url: null
<prototype>: Object { constructor: e()

Notice me if i forget something important, any help would be appreciated, thx.
