I am working on multi-tenant approach. I created a new tenant with all its information in database including its sub-domain. My approach is separate database and separate sub-domains for each customer. So, I am creating a sub-domain on button click and saving it in database. Now, I am lost on my way how to redirect that sub-domain to main page. I just need to redirect it to main page nothing else, I will work on separate db connection later. I also created the wildcard subdomain entry from cpanel. I am working on wildcard domains for the first time and also I am on my way of learning laravel.

Here is my code:

routes/web.php

Route::group(array('domain' => '{account}.example.com/tracker'), function()
{
      Route::get('/', 'HomeController@index');

});

HomeController.php

<?php

    namespace App\Http\Controllers;

    use Illuminate\Http\Request;

    class HomeController extends Controller
    {

          public function index()
          {
                return view('welcome');
           }
    }

I know there are lot of things missing that's why its not working but I tried many solutions I found on google but still I am unable to figure out what I am doing wrong. Please help me how to overcome this issue.

Thank you
