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

Do you have the OpenSSL libs somewhere in your path?

which version of Qt are you using? 5.12.4 or newer will require a newer version of OpenSSL - https://community.esri.com/community/developers/native-app-developers/arcgis-runtime-sdk-for-qt/blog... 

On Windows those are libcrypto-1_1-x64.dll and libssl-1_1-x64.dll.

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.
