This layer uses the OpenStreetMap API to download and display raster images.

The OpenStreetMap API provides maps only in one specific Projected System (WGS 84 / Pseudo-Mercator, EPSG: 3857). Therefore layers of these types will only be displayed in the map view if the Coordinate system setting in the map view settings  is set to this specific coordinate system. (in Redbex the WGS 84 / Pseudo-Mercator, EPSG: 3857 system is one of the predefined projected systems installed with every Application Server Database).
