some map layers based on .png files are not loaded on webEngine

filipdns

Hello,

I want to load web page in QML and I'm using:

    Rectangle {
        anchors.fill:parent
        visible:true
        color: "black"

        WebEngineView {
            anchors.fill: parent
            url: "https://www.flightradar24.com/46.70,2.26/5"

        }
    }

All is working fine but this page have some layers with .png file based on "url" and some of them are showed (e.g: "https://tiles.flightradar24.com/atc_boundaries/6/31/21/tile.png") but other are not (e.g: "https://adn4.velocityweather.com/v1/pE1XIsihsRlS/tms/1.0.0/C09-0x0316-0+Standard-Mercator+2020-01-15T09:50:01Z/7/67/83.png?ts=1579084800&sig=gEYtTxby54aMgJHp9SQJ7dUjZJg=" is not show , do you know why?

I try to load directly the not showed .png with:

    Rectangle {
        anchors.fill:parent
        visible:true
        color: "black"

        WebEngineView {
            anchors.fill: parent
            url: "https://adn4.velocityweather.com/v1/pE1XIsihsRlS/tms/1.0.0/C09-0x0316-0+Standard-Mercator+2020-01-15T09:50:01Z/7/67/83.png?ts=1579084800&sig=gEYtTxby54aMgJHp9SQJ7dUjZJg="

        }
    }

and it's working fine, then, it's not url problem...

I open https://www.flightradar24.com/46.70,2.26/5 in iexplorer / firefox and chrome and all it's working fine in all of them
