No map display in QWidget

Question

Hi

I build a very simple example from Qt Creator, without using Qml.

I test my license it seems to be OK, return 3 (Valid) and Initialize rturn true.

But nothing can be display on map (I try Raster, OpenstreetMap).

I have a flood on console with this message :

qt.network.monitor: Failed to subscribe to network connectivity events: "CoInitialize n’a pas été appelé."

qt.network.monitor: failed to start network status monitoring

Any ideas ?

Regards

Thank you for your help Lucas !

we see this error too. It seems to be something coming from Qt itself and we have not been able to identify any actual problems associated with the warning.
