how to remove nginx welcome page?

I’ve been setting up my domains using Nginx.

I’ve managed to set up everything but now my website only displays ‘Welcome to nginx’, ‘If you see this page, the nginx web server is successfully installed and working. Further configuration is required.’

I have no clue how to fix this.

This is my etc/nginx/sites-available/daanvandalen.com: *

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

        root /var/www/daanvandalen.com;
        index index.html index.htm index.nginx-debian.html;

        server_name daanvandalen.com www.daanvandalen.com;

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

And this is the default one:
