nginx reverse proxy Angular Node app mixed content http requests - javascript

I'm dealing with nginx and node express server, the app used to works fine with reverse proxy over port 80 but the issue started when i installed a SSL with certbot over nginx, i've been trying also with https node module but i'm still getting mixed content error when i make requests from my angular front to my node backend. I think it's a bad traffic configuration over nginx, maybe i need to set traffic from nginx to node server (port 3000) with http but i'm not sure how to achieve that. Thanks in advance.
Console error when requests:
polyfills-es2015.aa82454585d558e1759e.js:1 Mixed Content: The page at 'https://www.example.com/signup' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://myVpsIpNumber:3000/api/register'. This request has been blocked; the content must be served over HTTPS.
This is my nginx set:
server {
server_name example.com www.example.com;
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}

ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {

return 301 https://$host$request_uri;

if ($host = example.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
server_name example.com www.example.com;
return 404; # managed by Certbot
}
my express server:
const express = require('express');
const cors = require('cors');
let app = express();
//routes
const user_routes = require('./routes/user.router');
// middlewares
app.use(cors());
app.use(('/'), express.static('client', {redirect: false}));
app.use('/api', user_routes);
app.get('*', function(req, res, next){
res.sendFile(path.resolve('client/index.html'));
})
// start server
app.listen(3000, () => console.log('Server started at port : 3000'));
Angular service:
import { HttpClient, HttpHeaders } from '#angular/common/http';
noAuthHeader = { headers: new HttpHeaders({ 'NoAuth': 'True' }) };
constructor(private http: HttpClient) {}
postUser(user: User){
return this.http.post('http://localhost:3000/api' + '/register', user, this.noAuthHeader);
}
node backend:
register: (req, res, next) => {
let user = new User();
user.email = req.body.email;
user.password = req.body.password;
user.save((err, doc) => {
if (!err)
res.send(doc);
else {
if (err.code == 11000)
res.status(422).send(['Email ya registrado']);
else
return next(err);
}
});
}

I had the same issue although not with Angular but Vuejs. With http everything worked fine but after installing SSL certificate with certbot I got the "mixed content" error. I'm a beginner and couldn't figure out how to have my frontend talk to backend. It took me quite a while to solve this, so I hope this helps:
Copy your "dist" folder in which you store your production build in this directory /var/www/html like so
$ cp -r /usr/src/app/dist/* /var/www/html
Nginx default file at /etc/nginx/sites-available/default should look like this:
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/html;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html;
server_name _;
location / {
try_files $uri $uri/ =404;
}
}
server {
root /var/www/html;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html;
server_name www.example.com example.com; # managed by Certbot
location / {
try_files $uri $uri/ =404;
}
location /api {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = www.example.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = example.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 ;
listen [::]:80 ;
server_name www.example.com example.com;
return 404; # managed by Certbot
}
In frontend use https://example.com/api instead of http://localhost:3000/api like so (not sure if this is working in Angular exactly like this, but you get the point):
postUser(user: User){
return this.http.post('https://example.com/api' + '/register', user, this.noAuthHeader);
}
app.js file looks ok. So no changes should be necessary.

The problem was in API calls from frontend, the solution is replacing the URL with the SSL domain (using https://).
Development:
'http://localhost:3000'
Production:
'https://www.example.com'
import { HttpClient, HttpHeaders } from '#angular/common/http';
noAuthHeader = { headers: new HttpHeaders({ 'NoAuth': 'True' }) };
constructor(private http: HttpClient) {}
postUser(user: User){
return this.http.post('https://www.example.com/api' + '/register', user, this.noAuthHeader);
}

NextJS FetchError ETIMEDOUT

I deployed my project on centos 7 that port forwarded to 8080 which means, we use the site using ip then :8080. And here is the NGINX config I used for my front-end and backend reverse proxy
Site nginx config
server {
listen 80;
listen [::]:80;

proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
#proxy_cookie_path / "/; SameSite=lax; HTTPOnly; Secure";
}
}
I got this error
FetchError: request to http://ipaddress:8080/auth/checkauth failed, reason: connect ETIMEDOUT ipaddress:8080

urlClone.pathname = `/404`;
const res = await fetch(`${process.env.NEXT_PUBLIC_API_URL}/auth/checkauth`, {
method: 'GET',
headers: {
Authorization: `Bearer ${token.app_token}`,
},
});
if (res.status === 200) {
return NextResponse.next();
}
return NextResponse.rewrite(urlClone);
}
The app works fine in production, also with my Axios api. I can login thru my app using axios request but my middleware that have fetch api and getServerSideProps that also have fetch api having connect ETIMEDOUT error.
What I tried so far
proxy agent
change fetch api to axios with adapter
tried playing with url
set cors on my API to all and true
I can also call my api endpoint using curl inside the server and postman on my local machine
My other NextJS app that being deployed in linux server same procedure also, it does have fetch api in middleware and getServerSideProps works fine but that server is not port forwarded to any port. I'm wondering if that could be the issue
I used NextJS v12.1.6
I solved this by replacing my await fetch base url to localhost http://127.0.0.1:3333 (api host) on the server. Works perfect on my case.
const res = await fetch(`http://127.0.0.1:3333/auth/checkauth`, {
method: 'GET',
headers: {
Authorization: `Bearer ${token.app_token}`,
},
});

Nginx audio files (wav/ogg/mp3) not working

Audios on prod are not working while working fine on dev environment (Angular 7).
Prod config (VPS):
Ubuntu 18
Nginx
Let's encrypt
AudioService:
export class AudioService {
audio = new Audio();
constructor() { }
isPlaying() {
return this.audio.currentTime > 0 && !this.audio.paused && !this.audio.ended && this.audio.readyState > 2;
}
play(name: string): void {
this.audio.src = `assets/audio/${name}`;
this.audio.crossOrigin = 'anonymous';
this.audio.load();
if (!this.isPlaying()) {
this.audio.play();
}
}
pause(): void {
if (this.isPlaying()) {
this.audio.pause();
}
}
}
CORS are enabled on Nodejs side (using Nestjs). main.ts:
app.enableCors();
Chrome log:
Uncaught (in promise) DOMException: Failed to load because no
supported source was found.
Firefox log:
NotSupportedError: The media resource indicated by the src attribute
or assigned media provider object was not suitable.
Looking at Network console we can see myaudio.wav with:
Status Code: 206 Partial Content
Note: Loading images works fine !
EDIT:
Nginx config /etc/nginx/sites-available/mywebsite:
# Redirection

# return 301 https://$host$request_uri;
# } # managed by Certbot

ssl_certificate /etc/letsencrypt/live/mywebsite.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/mywebsite.com/privkey.pem; # managed by Certbot
}
On dev environment localhost:4200/assets/audio/myaudio.wav → works fine
On prod environment https://mywebsite.com/assets/audio/myaudio.wav → returns home page
While https://mywebsite.com/assets/image.jpg → works fine
Only audios don't work.
Set max_ranges to 0.
For your case, this would look like something like this:
location ~ \.wav$ {
max_ranges 0;
}
Meaning the rule applies to every wav file regardless of their location.

How to correctly configure Nginx for Node.js REST API?

I have a node application running on a service with Apache and Nginx as a reverse proxy.
On the same server also a Node REST API is running.
The JavaScript code looks as follows:
api.js
// Express
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
// Express App
const app = express();
// Env
const PORT = process.env.PORT || 3000;
const NODE_ENV = process.env.NODE_ENV || 'development';
// Config
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cors());
// Routes
const users = require('./routes/users');
// Angular Http content type for POST etc defaults to text/plain at
app.use(bodyParser.text(), function ngHttpFix(req, res, next) {
try {
req.body = JSON.parse(req.body);
next();
} catch(e) {
next();
}
});
app.use('/api', users);
app.listen(PORT, function() {
console.log('Listen on http://localhost:' + PORT + ' in ' + NODE_ENV);
});
/routes/users.js
var models = require('../models');
var express = require('express');
var router = express.Router();
// get all users
router.get('/users', function(req, res) {
models.Beekeeper.findAll({}).then(function(users) {
res.json(users);
});
});
module.exports = router;
The Nginx configuration looks as follows:
index index.html index.htm;
upstream api {
server 127.0.0.1:3000;
}
server {
listen 80;
server_name example.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443;
root /var/www;
ssl on;
ssl_prefer_server_ciphers On;
ssl_protocols TLSv1.2;
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 10m;
ssl_ciphers AES256+EECDH:AES256+EDH:!aNULL;
add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;
ssl_dhparam /etc/nginx/ssl/dhparam.pem;
ssl_certificate /etc/letsencrypt/live/example.com/cert.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
server_name example.com;
location / {
proxy_pass http://127.0.0.1:8000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-Ip $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /api {
proxy_pass http://api;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-Ip $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
rewrite ^/api/?(.*) /$1 break;
proxy_redirect off;
}
}
The problem is that if I make an API call on my development server, for example, localhost:3000/api/users, it works as expected.
However, if I make an API call on my production server, for example, https://example.com/api/users, I get Cannot GET /users and 404 NOT FOUND, respectively.
I suppose that there is something wrong with my Nginx configuration, however, although I already read numerous other posts about similar problems here on Stackoverflow, I could not solve the problem.
Notice that you're requesting this:
https://example.com/api/users
But the error says this:
Cannot GET /users
So the /api prefix is being stripped off the request path before being passed to your Node server.
Which is done by this line:
rewrite ^/api/?(.*) /$1 break;
Solution: remove that line.

Redirect to https not working (and https itself not working)

My goals are to get https to work, and then get the http to https redirections, and the non-www to www redirections to work.
Nginx.conf looks like:
http {
include mime.types;
default_type application/octet-stream;
types_hash_max_size 2048;
server_names_hash_bucket_size 64;
include site.conf;
server {
listen 8080;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
}
}
site.conf looks like:
upstream site_local {
server 127.0.0.1:9090 max_fails=3 fail_timeout=20s;
}
server {
listen 80;
server_name site.com;
return 301 https://www.site.com$request_uri;
}
server {
listen 80;
server_name www.site.com;
return 301 https://www.site.com$request_uri;
}
server {
listen 443;
server_name www.site.com;
set $app_root /home/site/site-web-node/public;
ssl on;
ssl_certificate /etc/ssl/SSL.crt;
ssl_certificate_key /etc/ssl/site.key;
location / {
proxy_pass https://site_local;
client_max_body_size 10m;
client_body_buffer_size 128k;
}
location ~ /(app|lang|js) {
root $app_root;
}
}
service nginx reload is successful, however the website's https isn't working, nor the redirects. http is working as before.
nginx -t returns successful.
I am getting the same error
Its show me like this when i run sudo netstat -tlnp | grep 443
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 10031/nginx
Then i found it was the site available server config file was the problem. Its working now.

config nginx for multiple nodejs apps

hello i have to config multiple apps of nodejs using nginx...
this is my actual configuration
upstream domain.com.ar {
server 127.0.0.1:9000;
}
server {
listen 80;
server_name www.domain.com.ar;
rewrite ^/(.*) http://domain.com.ar/$1 permanent;
}
server {
listen 80;
listen [::]:80 ipv6only=on;
server_name domain.com.ar;
#access_log /var/log/nginx/domain.com/access.log;
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://domain.com.ar;
proxy_redirect off;
}
}
when i use the ip 190.213.125.17:9000 (its just an example of my ip) the app works fine
but when i try to use the domain.com.ar nginx redirect to this page
http://domain.com.ar/cgi-sys/defaultwebpage.cgi
so the app respond with a 404 error configured by me in my app.js like a middleware
app.use(function(req, res, next){
res.render('404.jade',
{
title: "404 - Page Not Found",
showFullNav: false,
status: 404,
url: req.url
});
});
there is something wrong in the nginx config???
