Hi,
You will get error with QGIS as well if you zoom till level 20. You can see the
requests that QGIS creates by opening the debug window with function key 12.
Here is one that fails.

Level 19 works
https://maps.wien.gv.at/basemap/bmaporthofoto30cm/normal/google3857/19/183249/283150.jpeg
They perhaps use also some load balancing system but using server address
maps.wien.gv.at vs. maps1/wien.gv.at does not seem to make any difference. So
the error seems to be due to error in GetCapabilities that claims that zoom
level 20 is supported. You can get image data by selecting the zoom level
manually with an open option "zoom_level".

Aihe: [gdal-dev] gdal_translate wmts.xml wmts.tif: 0ERROR 4:

Hi GDAL community,
I have an GDAL_WMTS XML file containing the information for:
https://eur06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.basemap.at%2Fwmts%2F1.0.0%2FWMTSCapabilities.xmldata=05%7C01%7Cjukka.rahkonen%40maanmittauslaitos.fi%7C347da3139e62450e8ab008da73d82cdf%7Cc4f8a63255804a1c92371d5a571b71fa%7C0%7C1%7C637949669584791800%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7Csdata=792LjHXGRON13LHTJ8SR%2FVQZbyPegrlygXVRudCay4U%3Dreserved=0bmaporthofoto30cmnormalgoogle385710719646000873107344559993854true204,404true
When I'm opening the xml file in QGIS, the correct tile defined above in the
XML will be shown.
When I do
gdal_translate bmortho77.xml bmortho77.tif
then I get:
Input file size is 9921, 9968
