Hi all,
I have problems creating the correct mapproxy-grid. Maybe someone can
help me?!

Problems:
=========
1. check wmts via qgis (see url above): map is visible. At zoom 0 the
urls of tiles with maps have a range between
TileCol [160..171]
TileRow [131..140]
see for example (Pforzheim):
<http://rips-caches.lubw.baden-wuerttemberg.de/arcgis/rest/services/RIPS_TK_Cache/MapServer/WMTS/tile/1.0.0/RIPS_TK_Cache/default/default028mm/0/135/165.png>
2. if I check the wmts in mapproxy-demo, no map is visible. Following
errors are seen:
[2019-06-03 17:35:53,563] mapproxy.source.request - INFO - GET
https://rips-caches.lubw.baden-wuerttemberg.de/arcgis/rest/services/RIPS_TK_Cache/MapServer/WMTS/tile/1.0.0/RIPS_TK_Cache/default/default028mm/0/10/4.png
404 - 151
[2019-06-03 17:35:53,563] mapproxy.source.tile - WARNING - could not
retrieve tile: HTTP Error
"https://rips-caches.lubw.baden-wuerttemberg.de/arcgis/rest/services/RIPS_TK_Cache/MapServer/WMTS/tile/1.0.0/RIPS_TK_Cache/default/default028mm/0/10/4.png":
404
At zoom 0 the urls of tiles with maps have a range between
TileCol [4..7]
TileRow [6..10]
Do I have to set an offset? (Is this possible?) I tried to use the bbox
in utm32-coordinates. No effect.
Thanks in advance!
