MapViewer: Cannot fetch map tile

[dalishi]

Hi, Im running MapViewer example and the map is not shown.

The error message is:

QML debugging is enabled. Only use this in a safe environment.
QGeoTileProviderOsm: Tileserver disabled at  QUrl("http://maps-redirect.qt.io/osm/5.8/satellite")
QGeoTileFetcherOsm: all providers resolved

OSM server might be blocked in my place and i'm using a VPN server. How should I configure this to show the map correctly? Thanks.

I think you answered your own question. If you don't have OSM access then you don't

@Kent-Dorfman with a VPN, i can open the OSM web page. I just dont know how to configure osm plugin to use VPN.

@dalishi said in MapViewer: Cannot fetch map tile:

http://maps-redirect.qt.io/osm/5.8/satellite

Returns a definition for a tile provide that is explicitly disabled.

chrisw@newton:/tmp$ curl http://maps-redirect.qt.io/osm/5.8/satellite
{
    "Enabled" : false,
    "UrlTemplate" : "http://basemap.nationalmap.gov/arcgis/rest/services/USGSImageryOnly/MapServer/tile/%z/%y/%x",
    "ImageFormat" : "jpg",
    "QImageFormat" : "RGB888",
    "ID" : "usgs-l7",
    "MaximumZoomLevel" : 8,
    "MapCopyRight" : "<a href='http://basemap.nationalmap.gov/arcgis/rest/services/USGSImageryOnly/MapServer'>USGS The National Map: Orthoimagery</a>",
    "DataCopyRight" : "<a href='http://landsat.gsfc.nasa.gov/?page_id=2339'>USGS/NASA Landsat</a>"
}

Presumably this was disabled by the Qt crowd for a reason (probably asked to). The URL template does not look like OSM. Nevertheless, the URL template does actually return data:

https://basemap.nationalmap.gov/arcgis/rest/services/USGSImageryOnly/MapServer/tile/8/136/74

I think the question is more, "How do I define a provider to a tile server I can use?"
