Qml FolderListModel fails to access shared folder - qt

Question

I have a program in Qt/Qml that uses a FolderListModel to list qml files in a folder
FolderListModel {
id: progModel
folder: "file:///" + application.dirPath()
Component.onCompleted: console.log("folder: " + folder)
}
This model is passed to a ListView
ListView{
id: gridContent
model: progModel
delegate: progDelegate
}
It works well when the application runs in the Windows host, however if I share the application folder and try to run it from other Windows OS then the application fails to detect the folder.
Now we are using the Qt 5.9.3 and QtQuick 2.3. Before it worked well, when it was used Qt 5.5 and QtQuick 1.0
Note: If I put the URL showed from the console.log, something like "file://my_remote_path" the Windows Explorer open the folder correctly.
I have written a small piece of code to make the problem more clear
import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.0
import Qt.labs.folderlistmodel 2.1
ApplicationWindow {
visible: true
width: 640
height: 600
title: qsTr("Hello World")
SwipeView {
id: swipeView
anchors.fill: parent
Page {
Rectangle{
id: rect1
color: "#cccccc"
anchors{top: parent.top; horizontalCenter: parent.horizontalCenter}
width: parent.width * 0.6
height: parent.height*0.9
FolderListModel{
id: progfolder
showDirs: true
showDirsFirst: true
folder: "file://quatro/visao/qml/reportDialog" // It does not work
//folder: "file:///programming/comm5-qt5.6/visao/test/qml/reportDialog" // It works
//folder: "file:///programming/comm5-qt5.6/visao/reportDialog.lnk" // It works
nameFilters: ["*.qml"]
Component.onCompleted: console.log("folder " + folder)
}
ListView{
id: lv
anchors.fill: parent
model: progfolder
delegate: progDelegate
}
Component{
id: progDelegate
Text{
text: fileName
}
}
}
}
}}
This time I run the program say in PC2 but set the folder property to a shared folder in PC1, say "file://quatro/visao/qml/reportDialog". The problem is the same.
I have also comment two other ways to set the folder property. If I choose a local folder there is no problem. If I use a link to the share folder it also works but if I try to set the remote path it does not work.
