The property expires does not exist on hipanel\modules\server\models\Server. Since you implemented __get, consider adding a @property annotation.

        $this->label = Yii::t('hipanel:server', '(not sold)');

The property label does not exist. Although not strictly required by PHP, it is generally a best practice to declare properties explicitly.

        if (!empty($expires)) {
            if (strtotime($expires) < time()) {
                $class = 'danger';
            } elseif (strtotime($expires) < strtotime('+5 days', time())) {
                $class = 'warning';
            } elseif (strtotime($expires) < strtotime('+30 days', time())) {
                $class = 'info';
            } else {
                $class = 'default';
            }

            $this->color = $class;

The property color does not exist. Although not strictly required by PHP, it is generally a best practice to declare properties explicitly.

            $this->label = Yii::$app->formatter->asDate($expires);
        }
