Hello, I've got this problem with the Auth::user() object not working properly when using subdomains. I'm running my local development website using XAMPP on localhost and I've got the subdomains admin.localhost and boards.localhost.

/*
    |--------------------------------------------------------------------------
    | Session Cookie Domain
    |--------------------------------------------------------------------------
    |
    | Here you may change the domain of the cookie used to identify a session

    |
    */

    'domain' => false,

I get the error trying to get property of non-object. I've made multiple google searches and looked through various pages but nothing has solved my problem. I've tried these variations:

    'domain' => 'localhost'
...
    'domain' => '.localhost'
...
    'domain' => '*.localhost'

but no better results from that. Could someone guide me to a proper solution or is a custom solution required?
