Nginx shows default page

Hello,

I followed this tutorial to install Nginx on my droplet but I still see the “Welcome to nginx!” page instead of my home page.

Here’s the content of my config file:

/etc/nginx/sites-available/mydomain.com

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

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

        server_name mydomain.com www.mydomain.com;

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

Also, when I run sudo nginx -t command, I get the following:

nginx: [warn] conflicting server name "mydomain.com" on 0.0.0.0:80, ignored
nginx: [warn] conflicting server name "www.mydomain.com" on 0.0.0.0:80, ignored
nginx: [warn] conflicting server name "mydomain.com" on [::]:80, ignored
nginx: [warn] conflicting server name "www.mydomain.com" on [::]:80, ignored
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Please assist.

Thank you.
