Thanks, Bobby I will do that right away

Hey, Bobby, I do have all these in my FastCGI conf file, my question is what exactly should be the contents of the WordPress conf file?
I have FastCGI installed and enabled already, this is what its config file in /etc/nginx/sites-available look like:

server {
        listen 80;
        root /var/www/html;
        index index.php index.html index.htm index.nginx-debian.html;
        server_name localhost;

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

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        }

        location ~/\.ht {
                deny all;
        }


}

And that for WordPress currently looks like this:

server {
        listen 80;
        root /var/www/html;
        index index.php index.html index.htm index.nginx-debian.html;
        server_name localhost;

        location / {
                # try_files $uri $uri/ =404;
                try_files $uri $uri/ /index.php$is_args$args;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        }

        location = /favicon.ico { log_not_found off; access_log off; }
    location = /robots.txt { log_not_found off; access_log off; allow all; }
    location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
        expires max;
        log_not_found off;
    }

        location ~/\.ht {
                deny all;
        }


}

What am I missing? It still gives a 403 error when I visit localhost.
