Hi there,

It is possible that the Nginx user does not have permission to access the /var/www/example.com directory. To verify that you could check your Nginx error log:

tail -100 /var/log/nginx/error.log

If this is the case make sure to change the owner of the files to the Nginx user.

Let me know how it goes.

Hi @emmanuelAngler,

Usually, if you want to host multiple domains on one Nginx service, I would recommend using different .conf files in the directory. Having said that, what you can do to make your subdomain load is to add it next to your examle.com domain on your server_name variable line:

server_name subdomain.example.com;

So it should look like this

server {
        listen 80;
        listen [::]:80;
        server_name subdomain.example.com example.com;
        root /var/www/example.com;
        index index.html
        location / {
           try_fules $uri $uri/ =404;
    }
}

If you want to optimize your Nginx app, I would suggest checking out the following DigitalOcean tutorial:
