Have had similar, to clear this, first check your session.php file and ensure that for you use a unique name for your cookie, then go on ahead and clear the browser cache of previously stored cookies, then check to see whether the problem still exists.

This approach helped me deal with mine

Thanks for your answer. What i have to change? Here is the session.php :

'driver' => 'native',	
'payload' => 'laravel_payload',

'expire_on_close' => 'false',
'cookie' => 'laravel_session',
'lottery' => array(2, 100),
'files' => storage_path().'/sessions',

Thanks, i was have the same problem (im working in two differents software with laravel) and the tharoldD answer solve it!
