I\'ve tried almost every available solutions

Answer 1

Is your button to disconnect in a form? If so, you need to put this: {{ csrf_field }} in your form of type POST.

Answer 2

Maybe the form has not declared the input tag of the token:

<input type="hidden" name="_token" value="{{ csrf_token() }}">

Answer 3

Go to config/session file and check if you have this line below:

'domain' => env('SESSION_DOMAIN', null)

If yes, then visit your .env file and also set like this:

SESSION_DOMAIN=null

Then refresh, should be fine.

Answer 4

You error may be coming from your session manipulation. When you do

Auth::attempt($data)

The user is already set in the session. You don't need to do your Session::put() thingy. To get the user, do

$user = Auth::user();

To logout, you do

Auth::logout(); //will clear the user from the session automatically

So to summarise, remove all the session manipulations you have in your code. Only play with Auth;

Session::flush(); //DELETE THIS LINE

Add Auth to the top of your controller with

use Auth; //easier to work like that.
