qml osm offline tiles

[finman]

Hello everyone. How do I implement an offline map. I tried to use the MS4W server, but it shows something wrong (even if i am delete the tiles directory(map folder) from the server), the application takes them from somewhere. My code is simple:

import QtQuick 2.15
import QtQuick.Window 2.15
import QtLocation 5.12

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Plugin {
        id: plugin_osm
        name: "osm"
        PluginParameter {
            name: "osm.mapping.custom.host"
            value: "http://127.0.0.1/map/"
        }

    }

    Map {
        id: map
        anchors.fill: parent
        plugin: plugin_osm
        zoomLevel: 1
        activeMapType: supportedMapTypes[supportedMapTypes.length - 1]
    }
}

files on the server:
