Nginx нестандартная ошибка timeout 504?

Дмитрий, не думаю что проблема с php кодом, так как код работал без проблем несколько лет.

php код

public function actionCreate($type)

    {   
        $model = new Content();
        $model->permission = 1;
        $model->keywords_uz = [14];

        $model->keywords_en = [16];
        $model->views = 0;
        if($model->load(Yii::$app->request->post())){
            if($model->id == null){
                $model->id = Content::find()->orderBy(['id' => SORT_DESC])->one()->id + rand(10, 20);
