Serving two different root folders from ngix

Hi, I’ve got a working server running nginx with the site information below

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

    root /var/www/app1/public;

    index index.php;

    server_name 12.23.456.789;

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

    location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
    }


    location ~ /\.ht {
    deny all;
    }

}

server { listen 8080; listen [::]:8080;

    root /var/www/app2/public;

    index index.php;

    server_name 12.23.456.789;

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

    location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
    }


    location ~ /\.ht {
    deny all;
    }

}

Unfortunately I can not manage the get the same working setup in DigitalOcean Droplet… Any ideas might might be the case or what am I missing? Just getting errors about conflicting server name

conflicting server name “12.23.456.789” on 0.0.0.0:80, ignored conflicting server name “12.23.456.789” on [::]:80, ignored conflicting server name “12.23.456.789” on 0.0.0.0:8080, ignored conflicting server name “12.23.456.789” on [::]:8080, ignored
