I can't understand why in netbeans when running in webkit with a connector the page is reloaded?

Question

Webkit

Good night all.
Who knows why in NetBeans, when starting a project in an embedded WebKit with a connector, the Yii2 project is constantly reloaded?
As soon as the main page of the project is loaded completely in the browser, the page reload is immediately triggered. What's interesting is that when you run WebKit without the connector, everything works fine.
I also noticed that the reload on the project also occurs when running in chrome with a connector. Everything works fine without the connector.
Who faced (or who knows) tell me?
Googled and found nothing on the topic.
