@connor11528 lol awesome...sounds like it wasn't anything I thought of...nice find!

1. In App/Exception/Handler.php
2. Use Illuminate\Auth\AuthenticationException;
3. In render function add this instead of "return parent::render($request, $exception);"

public function render($request, Exception $exception) {

return $request->expectsJson()
        ? response()->json(['message' => $exception->getMessage()], 401)
        : redirect()->guest(route('login', ['account' => $request->route('account')]));

}

This happens to me a lot, it seems that the cookies don't match the file sessions after a deployment. Presumably because when I deploy using docker the memcached sessions are cleared and the cookie is now invalid.

Personally I use a standard form submission and no AJAX so the 419 really threw me off.

I think what I have to do after reading over this thread is to try running php artisan cache:clear because when I make a code change my composer script is not run.
