Oops! An Error Occurred The server returned a "404 Not Found". Symfony

Question

Can someone please enlighten me what causing this problem in symfony and how to solve it.

Oops! An Error Occurred The server returned a "404 Not Found".

I'm just new in symfony and cpanel.

I just uploaded my working SF application from my pc (localhost) to my server or CPANEL. CPanel doesn't have SSH access so I used FTP to upload all directories. The directory of the files like so.

home/swipecom

• cache
• contactless (Where SF directories live)
• public_html (/web the only SF directory)
• var
• ssl
• tmp
• public_ftp
• logs

I created .htaccess into public_html like so public_html/.htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteBase /web

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ app.php [QSA,L]
</IfModule>

Lastly, I configured app.php in something like this.

<?php

use Symfony\Component\HttpFoundation\Request;

/** @var \Composer\Autoload\ClassLoader $loader */

// $loader = require __DIR__.'/../app/autoload.php';
// include_once __DIR__.'/../var/bootstrap.php.cache';

$loader = require '/home2/swipecom/contactless/app/autoload.php';
include_once '/home2/swipecom/contactless/var/bootstrap.php.cache';

$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);

// When using the HttpCache, you need to call the method in your front controller instead of relying on the configuration parameter
//Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

When I try to access the app like so www.domain.com here's the response I received.

Oops! An Error Occurred

The server returned a "404 Not Found".

I think this is tutorial help you:

sudo a2enmod rewrite

Enabling mod_rewrite

.htaccess

.htaccess file :

DirectoryIndex app.php

<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]

    RewriteRule .? %{ENV:BASE}/app.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
   <IfModule mod_alias.c>
       RedirectMatch 302 ^/$ /app.php/
   </IfModule>
</IfModule>
