So, I wanted to have 2 different subdomains work on the same droplet. Added them through digitalocean console. Then created folders for both of them using node.js and express and set up ports for each of them by modifying /home/subdomain/bin/www file as follows:

var port = normalizePort(process.env.PORT || '3002');

I followed this guideand setup nginx for both domains. Then I used pm2 start www for both sites.

Both domains are working, only problem is that I have to type the port number in the url (ex: subdomain.domain.net:3001), otherwise both domains redirect to the 2nd domain.

My 1st website’s nginx config file.

server {
  server_name subdomain.domain.net;
  listen 80;
  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://my droplet's IP:3001;
    proxy_redirect off;
  }
}

My 2nd website’s nginx config file.

server {
  server_name subdomain.domain.net;
  listen 80;
  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://my droplet's IP:3002;
    proxy_redirect off;
  }
}

How can I get both domains working so that I don’t have to type the port number in the url?
