Stuck on nginx multisite Wordpress (LEMP)

Hi! I have read a lot about this, but I can’t figure it out why is not working for me. The idea is the following: I want to host several websites on a single droplet. The scheme is like this:

wargostudio.com -> stuck oncativosa.wargostudio.com -> working fine jalisco.wargostudio.com -> working fine

example2.com sub1.example2.com … etc

when I go to wargostudio.com, I get a blank page. In the error log, the server is trying to access /usr/share/nginx/html/ but** I have specified another path.** Whats going on?

Thanks very much, and sorry for the length of the question.

So my first domain is: wargostudio.com and the config file:

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    root /var/www/wargostudio;

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

    # include snippets/wp-supercache.conf;

    server_name wargostudio.com www.wargostudio.com;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }

    location ~ /.well-known {
        allow all; 
    }

}
server {
    # SSL configuration

    listen 443 ssl http2 default_server;
    listen [::]:443 ssl http2 default_server;
    include snippets/ssl-wargostudio.com.conf;
    include snippets/ssl-params.conf;
}

And one subdomain (oncativosa.wargostudo.com) is like this:

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

    root /var/www/oncativosa;

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

    server_name oncativosa.wargostudio.com;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }
}

And finally jalisco.wargostudio.com

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

        root /var/www/jaliscopaletas;

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

        include snippets/wp-supercache.conf;

        server_name jalisco.wargostudio.com;

#       location / {
#               try_files $uri $uri/ /index.php?$args;
#       }

        # Caching of media: images, icons, video, audio, HTC
        location ~* \.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm)$ {

                add_header Cache-Control "public";
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }

        # CSS and Javascript
        location ~* \.(?:css|js)$ {
                expires 1d;
                add_header Cache-Control "public";
        }


        location ~ /\.ht {
                deny all;
        }
}
