How to handle network errors

[elaf]

I have an application using QtWebEngine on Linux. While I have an active connection to a webserver (e.g. a page is loading) my network interface gets a new ip and the webengine breaks with message net::ERR_NETWORK_CHANGED.

Is there a way to handle this errors within qml or in Qt? Something like
WebEngineView { onNetworkError:{ someErrorHandler( errorNumber ) } }?

Or is there a way to handle this errors in QQmlApplicationEngine?
