App not working without www

I have a subdomain in a cPanel where i added the ip of my Meteor app hosted on DigitalOcean.

The app works if accessed by www.subdomain.domain.com, but does NOT work if accessed without www.

How can i fix this issue?


I tried this solution , by editing nginx.conf, and adding the code at the end of the http {} part, but i am getting errors when doing service nginx restart.

server {
    listen       80;
    server_name  example.com;
    return       301 http://www.example.com$request_uri;
}

server {
    listen       80;
    server_name  www.example.com;
}

Can you post your entire nginx site config? (e.g. the full contents of /etc/nginx/sites-enabled/default if you’re using the default site config file) Also, what errors are you seeing when you restart nginx?

Content of /etc/nginx/sites-enabled/default

server {
        listen 80 default_server;
        listen [::]:80 default_server;

        root /var/www/html;

        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location / {
                try_files $uri $uri/ =404;
        }

Errors while service nginx restart

Job for nginx.service failed because the control process exited with error code. See “systemctl status nginx.service” and “journalctl -xe” for details.

Inside journalctl -xe i there are also some errors like this: Failed to start A high performance web server and a reverse proxy server.
