I am using nodejs.
When I try to access a route other than “/”, I receive 404 not found.

It works
https://www.celr.com.br

It does not work
https://www.celr.com.br/rfid

nginx/sites-available/celr.com.br file

server {

        root /var/www/celr.com.br/html;
        index index.js index.html index.htm index.nginx-debian.html;

        server_name celr.com.br www.celr.com.br;

        location / {
                try_files $uri $uri/ =404;
                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/celr.com.br/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/celr.com.br/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 ($host = www.celr.com.br) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


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


        listen 80;
        listen [::]:80;

        server_name celr.com.br www.celr.com.br;
    return 404; # managed by Certbot

}

index.js file

const express = require("express");
const app = express();
const multer = require("multer");
const path = require("path");

const storage = multer.diskStorage({
    destination: function (req, file, cb) {
        cb(null, "upload/");
    },
    filename: function (req, file, cb) {
        cb(null, file.originalname + Date.now() + path.extname(file.originalname));
    }
})
const upload = multer({storage});

app.set("view engine", "ejs");

app.get("/", (req, res) => {
    res.render("index");
});

app.get("/rfid", (req, res) => {
    res.render("caminhao");
});

app.post("/upload", upload.single("file"), (req, res) => {
    res.send("Arquivo recebido");
});

app.get("/face", (req, res) => {
    res.send("resposta");
    // res.render("face");
});

app.listen(3000, () => {
    console.log("servidor rodando");
});

I so a lot of answers here, but none of them helped me.
Thanks in advance.

Hi there @claudineigoncalves,

I think that you don’t need the try_files $uri $uri/ =404; part in your Nginx server block.

You can take a look at this tutorial here on how to set up NodeJS with Nginx:

https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-16-04#set-up-nginx-as-a-reverse-proxy-server

Hope that this helps!
Regards,
Bobby

Node.js is an open source JavaScript runtime environment for easily building server-side and networking applications. Node.js applications can be run at the command line but this guide focuses on running them as a service using PM2, so that they will automatically restart on reboot or failure, and can safely be used in a production environment.
