I am trying to implement static and dynamic subdomain routing in my application. It is not working as expected. I am using WAMPServer in my local machine.
routes.php
Route::get('/', 'WelcomeController@index');
Route::group(['domain' => 'api.letsplay.dev'], function () {
    Route::group(['prefix' => 'v1'], function () {
        Route::get('users', function () {
            return "Success";
        });
    });
});
php artisan route:list gives this
+------------------+----------+----------+------+----------------------------------------------+------------+
| Domain           | Method   | URI      | Name | Action                                       | Middleware |
+------------------+----------+----------+------+----------------------------------------------+------------+
|                  | GET|HEAD | /        |      | App\Http\Controllers\WelcomeController@index | guest      |
| api.letsplay.dev | GET|HEAD | v1/users |      | Closure                                      |            |
+------------------+----------+----------+------+----------------------------------------------+------------+
hosts file has this
127.0.0.1       localhost
127.0.0.1       hosp.dev
127.0.0.1       letsplay.dev
I use the .htaccess file provided by the laravel framework without any change
<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>
    RewriteEngine On
    # Redirect Trailing Slashes...
    RewriteRule ^(.*)/$ /$1 [L,R=301]
    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>
httpd-vhosts.conf
<VirtualHost *:80>
    ServerAdmin webmaster@letsplay.dev
    DocumentRoot "c:/wamp/www/letsplay-web/public"
    ServerName letsplay.dev
    ErrorLog "logs/letsplay.dev-error.log"
    CustomLog "logs/letsplay.dev-access.log" common
</VirtualHost>
When I tried to hit letsplay.dev from my browser, It is working as expected. but while trying to hit api.letsplay.dev/v1/users, I get ERR_ICANN_NAME_COLLISION in Chrome and the below error from IE!
Help me to understand what am I missing!
