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".

Hi GDAL community,

I have an GDAL_WMTS XML file containing the information for:

<GDAL_WMTS><GetCapabilitiesUrl>https://eur06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.basemap.at%2Fwmts%2F1.0.0%2FWMTSCapabilities.xml&amp;data=05%7C01%7Cjukka.rahkonen%40maanmittauslaitos.fi%7C347da3139e62450e8ab008da73d82cdf%7Cc4f8a63255804a1c92371d5a571b71fa%7C0%7C1%7C637949669584791800%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&amp;sdata=792LjHXGRON13LHTJ8SR%2FVQZbyPegrlygXVRudCay4U%3D&amp;reserved=0</GetCapabilitiesUrl><Layer>bmaporthofoto30cm</Layer><Style>normal</Style><TileMatrixSet>google3857</TileMatrixSet><DataWindow><UpperLeftX>1071964</UpperLeftX><UpperLeftY>6000873</UpperLeftY><LowerRightX>1073445</LowerRightX><LowerRightY>5999385</LowerRightY></DataWindow><BandsCount>4</BandsCount><Cache

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
0ERROR 4: 
./gdalwmscache\eb9a2e93c079d3e8af23fb6be1373c11/8/9/89ffd475b3114e593c2e248e71685f10:

any idea?

thanks
