Failed to load resource: the server responded with a status of 405 (Not Allowed) needs help on nginx.conf

Question

I have full MERN stack app with AXIOS. On my localhost, the app works perfectly but when I deploy the app on nginx, all the POST request gets denied. I tried many solutions that I found on the web but doesn't work. I think it's CORS problem/ nginx config problem. Did I make Nginx.conf right? My node is running on localhost:8000, React on localhost:3000.

EDIT

Things that I have tried:

Nginx.conf:

server {
    listen 80;

server_name lovechangingtheworld.org;

location / {
    proxy_pass http://localhost:8000;
    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;
    }

}

Do I need this on node too?

router.use((request, response, next) => {
  response.header("Access-Control-Allow-Origin", "*");
  response.header(
    "Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS"
  );
  response.header("Access-Control-Allow-Headers", "Content-Type");
  next();
});

The nginx configuration that you have is wrong. For node app to be exposed through nginx you need a Reverse Proxy I have already answered a related question

nginx config for Reverse proxy using no SSL. server.

server {
    listen 80;

    server_name 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;
    }

}

Using SSL

server {

    listen 443;
    server_name example.com;

    ssl_certificate           /etc/letsencrypt/fullchain.pem;
    ssl_certificate_key       /etc/letsencrypt/privkey.pem;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    location / {

      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;

      # Fix the “It appears that your reverse proxy set up is broken" error.
      proxy_pass          http://localhost:3000;
      proxy_read_timeout  90s;

      proxy_redirect      http://localhost:3000 https://example.com;
    }
 }

In the example.com you put your domain that you have registered with the IP of your. If you dont have a domain you can test it by adding it in the hosts How to add an IP to hostname file

Example 127.0.0.1 example.com

Where ever you see http://localhost:3000; you put the IP and port of the internal node app. In case its in the same machine you leave it as localhost:port.

EDIT 1

In you case

server {
    listen 80;

    server_name lovechangingworld.org;

    location / {
        proxy_pass http://localhost:8000;
        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;
    }

}

EDIT 2

For nodemailer to work there are two ways.Lets say that nodemailer runs at port localhost:3000 Either use a port like lovechangingworld.org:8088 or create a subdomain like mail.lovechangingworld.org. Create file in sites-available touch mail.lovechangingworld.org 2. Add the configuration

Example 1 new subdomain:

server {
        listen 80;

        server_name mail.lovechangingworld.org;

        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;
        }

    }

Example 2 diferent port:

 server {
            listen 8088;

            server_name lovechangingworld.org;

            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;
            }

        }
