Openstreetmap images missing from network object
The background of a WinUI network widget does not display a map anymore. The background is provided by OpenstreetMap.
OpenstreetMap provides a tile or WMS service free of charge. The “free of charge” provision assumes a fair use policy; if you are using the application heavily, you will need to take a subscription, see also OpenstreetMap Acceptable Use Policy
Heavy use of other similar services by other providers will also require that you to take a subscription!
The AIMMS WinUI provides software to deploy these GIS services but the AIMMS WinUI does not provide these services themselves.
More information to change to a new service can be found via: Aimms Menu > Help > Contents and Index, and then search for GIS.

Mundialis provides the information together with OpenstreetMap:
