Is your nginx config correct? Did you run migrations and create your .env? Are you serving from the public directory? Did you use leading slashes for assets? There are a bunch of questions related to a blank page. Maybe increase the details of the question...like the steps you took and how it is hosted.

Here is an example config:

# FORGE CONFIG (DOT NOT REMOVE!)
#include forge-conf/YOUR-SITE/before/*;

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name YOUR-SITE;
    root YOUR-SITE root;

    # FORGE SSL (DO NOT REMOVE!)
    ssl_certificate /etc/nginx/ssl/YOUR-SITE/YOUR-SITE-cert/server.crt;
    ssl_certificate_key /etc/nginx/ssl/YOUR-SITE/YOUR-SITE-cert/server.key;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA';
    ssl_prefer_server_ciphers on;
    ssl_dhparam /etc/nginx/dhparams.pem;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.html index.htm index.php;

    charset utf-8;

    # FORGE CONFIG (DOT NOT REMOVE!)
   #include forge-conf/YOUR-SITE/server/*;

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

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/YOUR-SITE-error.log error;

    error_page 404 /index.php;

    if ($request_uri ~* "^(.*/)index\.php/?(.*)") {
        return 301 "$1$2";
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }

    location ~ /\.(?!well-known).* {
        deny all;
    }
}

# FORGE CONFIG (DOT NOT REMOVE!)
#include forge-conf/YOUR-SITE/after/*;

The fastest way to start debugging this is to open the main index.php file that nginx points to and add a simple

die('Working');

in it. If you see it, it's a PHP/Laravel issue. If you don't, it's an nginx issue.

After this, if you see the "Working" message, tail storage/logs/laravel.log file to see if anything got dumped there. The production environment isn't very verbose when it comes to errors.

@dlucian , thanks a lot, your answer helped me to solve the problem :) turned out, It was a nginx misconfiguration.

How about
