How to fix POST request 419 error? | Laravel 5.7

For two days, there is one problem displayed in my localhost (XAMMPP and OpenServer).

Sorry, your session has expired. Please refresh and try again. 

I tried to clear cache, route, views, sessions... and also generated new app key but they doesn't helpd to fix this problem. Everything is works in Real hosting. However, localhost (http://localhost:8000) does not work POST requests. I used Laravel Collections and

tags... I did all the answers in the forums but did not work anything. I also cleared browsers.. Now i have

{!! Form::open(array('url' => array('nuu-admin/directions/submit_direc'),'class'=>'','name'=>'category_form','id'=>'category_form','role'=>'form','enctype' => 'multipart/form-data')) !!} 
---
< form method="POST" action="{{ route('login') }}" >
                        @csrf

All of them doesn't work. Everytime displayed 419 error page!! How can i solve this problem? Please give some advice! Thanks!
