Can't login after logout Laravel

Question

I have developed a dynamic page with javascript (no reloading) where a user inserts a private number.

Then I send a Ajax request to manually log in the user associated with that number.

After that if the user wants he can exit (send Ajax request to logout) and the main page appears to log in again.

Steps To Reproduce:

Enter Number, click login and I verify that the first login works.
Click exit and the logout works
Insert same or another number and click login again and now the user is not authenticated.

Note: If I refresh the page after exit(logging out), the 2nd login works.

-> Code where I send Ajax request to verifyNIF()

$('#start').on('click', function() {

   
    $.ajax({
        url: '/' + slug + '/vote-in-person/verify-nif',
        type: "POST",
        data: {
            nif: nif
        },
        dataType: "json",
        success: function (data) {
            //NIF VERIFIED AND USER LOGGED IN
        }
    });

});

-> verifyNIF() verifies the number on the DB and then authenticates the user

Auth::login($user);

-> logout() function, which uses Laravel Fortify logout route.

function logout(){
    $.ajax({
        url: '/logout',
        type: "POST",
        success: function () {
            console.log("logged out");
            // location.reload();
        },
        error: function (data) {
            console.log(data);
        }
    })
}

could you show how the authentication works? I mean, how a request to the laravel backend is recognised as coming from an authenticated user? is a token shared in http headers? a cookie perhaps? — germanio, Jun 01 '21 at 19:05

On the front side, the CSRF token becomes invalid after logout with an ajax request. You can add a new endpoint to refresh the CSRF token manually. I think that helps you. https://stackoverflow.com/a/57252273/9215587
