Thanks.
The grids are not compatible, because the configured BBOX and resolutions do not result in complete tiles (the height of the BBOX 330000 / res. 250 px/m -> 1320px -> 5.15 tiles). The export tool handles that, when the grids are not compatible. But it did not recognize that the grids are incompatible in this special case and failed when it tried to access the tile directly.

Pushed a fix for that: https://github.com/mapproxy/mapproxy/commit/a5c28c16542559663fcd4b3d7e7c13f9ab6149e1
