Codeigniter 3 does not redirect to any controller. Getting 404.

Codeigniter welcome page loads but no other controller. This application is working on WAMP locally, but not working on Godaddy.
But another application using Codeigniter 2 works on the same server.
The server is VPS on Godaddy.

Thanks in advance for the support.
Here are the files.
***.config***
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

$config['base_url'] = 'http://mysite.com/ci3/';
$config['index_page'] = 'index.php';
$config['uri_protocol'] = 'REQUEST_URI';

***.htaccess***
<IfModule mod_rewrite.c>
RewriteEngine On

RewriteBase /ci3/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|assets|images|robots\.txt)
RewriteRule ^(.*)$ /ci3/index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.

ErrorDocument 404 /ci3/index.php
</IfModule>

PS: Searched through the forum couldnot find any solutions I have not tried while searching on google.

Search the forms for GoDaddy .htaccess
