Codeigniter Routing Problems

I have this website (php, CI, ubuntu, apache, mysql):
https://oneclickpy.com/
The homepage is working fine. But no one of the other pages works

My config.php:
$config['base_url'] = "https://oneclickpy.com";
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';

My routes.php:
$route['default_controller'] = "home";
$route['admin'] = "admin/login";
$route['apple'] = "home/apple";
$route['xiaomi'] = "home/xiaomi";
$route['samsung'] = "home/samsung";

My .htaccess:
  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond $1 !^(index\.php|assets|upload|robots\.txt|.*\.css)
  RewriteRule ^(.*)$ index.php?/$1 [L]

Rewrite mod is enabled on VPS.

It was working fine in other hosting, but not now on Digital Ocean.
When I open the website home, it's ok. But when trying to open other pages (like "apple", "samsung"), I got 404 error.

What can I do?
