<p>Here is the code.If sign in it goes to <code>/dashboard</code> route. but after I go to other route <code>user session</code> is not persisting(by dd I found this).thanks in advance if you solve, I spent hours on this. </p>

<pre><code>Route::group(['middleware' =&gt; 'web'],function(){

  Route::get('/', function () {
    return view('welcome');
  })-&gt;name('home');

  Route::get('/dashboard' , [
    'uses' =&gt; 'UserController@GetDashboard',
    'as' =&gt; 'dashboard'
    ]);

  Route::post('/signin' , [
    'uses' =&gt; 'UserController@postSignin',
    'as' =&gt; 'signin'
    ]);
});
</code></pre>

<pre><code>public function postSignin(Request $request)
  {
   if(Auth::attempt(['email' =&gt; $request['email'],'password' =&gt;       $request['password']])) {
  return redirect()-&gt;route('dashboard');
   }
  return redirect()-&gt;back();
