What is the best way to handle expired login forms (expired tokens)

If someone logs out and leaves their form open overnight and come back the following day and login they get an error due to the expired token.

I would like to handle this error and send them back to the login screen with a message that for security reasons their form had been inactive too long please login.

Using Laravel 5, looks like this should be setup in the Handler.php I gave this a try but it doesn't seem to be catching the error: if($e instanceof TokenMismatchException) { return redirect('login')->with('message', 'Your form had expired for security reasons. To prevent this refresh the login page prior to logging in.'); }

Thanks in advance.
