Laravel Project Not Running On Server - laravel-6

Question

I have deployed my laravel project on server. When I hit the url it gives me error but no log is generated in log folder.
This page isn’t working
[Domain Name] is currently unable to handle this request.
HTTP ERROR 500
I have moved the public folder contents to root directory and edited the index.php.
I checked the permission for storage, vendor and bootstrap folder and they have required permission.
index.php
<?php
define('LARAVEL_START', microtime(true));
require __DIR__.'/vendor/autoload.php';
$app = require_once __DIR__.'/bootstrap/app.php';
$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);
$response = $kernel->handle(
$request = Illuminate\Http\Request::capture()
);
$response->send();
$kernel->terminate($request, $response);
Server.php
<?php
/**
* Laravel - A PHP Framework For Web Artisans
*
* #package Laravel
* #author Taylor Otwell <taylor#laravel.com>
*/
$uri = urldecode(
parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH)
);
// This file allows us to emulate Apache's "mod_rewrite" functionality from the
// built-in PHP web server. This provides a convenient way to test a Laravel
// application without having installed a "real" web server software here.
if ($uri !== '/' && file_exists(__DIR__.'/public'.$uri)) {
return false;
}
require_once __DIR__.'/public/index.php';
.htaccess
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>
RewriteEngine On

</IfModule>
The project is hosted on shared hosting and I've used filezilla to upload it on server. What else I need to do to make it work. This is my first uploading the project on the server.
