New session per subdomain!

Hello im tryna make one auth session per domain! So here is more details.

I want to make something like that:

https://ultranetwork.buycraft.net http://ownagepe.buycraft.net/

All of that sites have own session and when loggin in in one of it in another site you must loggin in again. So here is my routes

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::group(['domain' => env('PLAIN_URL')], function () {
    Route::get('/', 'HomeController@index')->name('home');
    Route::post('/gdpr', 'HomeController@gdpr');
    Auth::routes();

// Main site cart
    Route::group(['prefix' => 'cart'], function () {
        Route::post('/checkout', 'CartController@page')->name('checkout');
        Route::get('/success', 'CartController@success')->name('purchaseSuccess');
        Route::get('/failed', 'CartController@failed')->name('purchaseFailed');
        Route::put('/proccess', 'CartController@proccess')->name('purchase');
        Route::get('/check', 'CartController@check')->name('check');
    });

});

// Shop things content
Route::group(['domain' => '{slug}.' . env('PLAIN_URL'), 'middleware' => 'ShopExist'], function () {
    Route::get('/', 'Shop\HomeController@page');
    Route::get('/language/{lang}', 'Shop\LanguageController@changeLang');
    Route::get('/currency/{currency}', 'Shop\CurrencyController@change');
    Route::get('/category/{category}', 'Shop\CategoryController@page');

    Route::group(['prefix' => 'auth'], function () {
        Route::get('/login','Shop\AuthController@page')->middleware('guest');
        Route::get('/logout','Shop\AuthController@logout')->middleware('auth');
        Route::post('/login','Shop\AuthController@create')->middleware('guest');
    });

});

My Session.php config

<?php

return [


    'driver' => env('SESSION_DRIVER', 'database'),


    'lifetime' => env('SESSION_LIFETIME', 120),

    'expire_on_close' => true,


    'encrypt' => true,


    'files' => storage_path('framework/sessions'),


    'connection' => null,


    'table' => 'sessions',


    'store' => null,


    'lottery' => [2, 100],


    'cookie' => 'myshopmcsession',


    'path' => '/',


    'domain' => env('PLAIN_URL'),


    'secure' => env('SESSION_SECURE_COOKIE', false),


    'http_only' => true,


    'same_site' => null,

];

So when you loggin in in one site to not log you in another!
