Forbidden You don't have permission to access this resource. - Production

Hello Team, I am trying to deploy my project to live using contaboserver but getting Forbidden You don't have permission to access this resource. Can you help me solve this...?

I also renamed server.php to index.php

This is my .htaccess

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

    RewriteEngine On

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ / [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

# php -- BEGIN cPanel-generated handler, do not edit
# Set the “ea-php71” package as the default “PHP” programming language.
<IfModule mime_module>
  AddHandler application/x-httpd-ea-php71 .php .php7 .phtml
