laravel 5.4 not working on subdomain - laravel

Question

Steps I followed till now:
create sub-domain.
uploaded project files of public inside public_html/subdomain-name/
create a folder subdomain-name in root
upload every files of laravel project except public folder inside subdomain-name folder
change 2 lines of index.php which is inside public_html/subdomain-name/ as to:
require __DIR__.'/../../../staging/bootstrap/autoload.php';
and
$app = require_once __DIR__.'/../../../staging/bootstrap/app.php';
And my htaccess files looks like:
<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
I am getting error as:
This page isn’t working
staging.mydomain.com is currently unable to handle this request.
HTTP ERROR 500
Can somebody guide me with this? Thank You

2. uploaded project files of public inside public_html/subdomain-name/
When you create a subdomain, a folder appears in your root directory, you should upload project files of public into created subdomain folder. ie (example.your site.com) and not into public_HTML/subdomain
You should also try this in your .htaccess
Options -MultiViews
RewriteEngine On
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
