Comment (by mlennert):

I can see in your message a call to:

[https://www.basemap.at/wmts/1.0.0/WMTSCapabilities.xml?SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=geolandbasemap&STYLE=normal&FORMAT=image/png&TILEMATRIXSET=google3857&TILEMATRIX=12&TILECOL=2188&TILEROW=1435]

This gives me the capabilities of the service, but not the tiles. In that
capabilities file, I see that to get the tile 2188,1435, I have to use the
following url:

[http://maps1.wien.gv.at/basemap/bmapgrau/normal/google3857/12/1435/2188.png\]

So it seems (but I'm really a complete newbie in WMTS) that maybe the
wrong URL is being called to get the tile...

yes it seems so; see [http://osgeo-

regarding ''driver=WMS_GDAL'', some tests showed that this is not the
correct r.in.wms GDAL driver (i.e. http://www.gdal.org/frmt_wms.html) for
this server, it should be used GDAL WMTS
(http://www.gdal.org/frmt_wmts.html). GDAL WMTS is available since GDAL
2.1.

that's not implemented yet, maybe worth for an enhancement ticket.

see #3129 for the enhancement ticket. I'm inclined to close this one.
