Hi Wolfgang, this seems to be some Qt internal warning. stateChanged() is a signal from a Qt socket class. We do not use sockets directly in the TMS implementation. We let QNetworkAccessManager do the details. I guess something fails while connecting to the server resulting in no socket (pointer to socket set to nullptr). And this is the reason why connecting the signal of this nonexistent socket fails. That's what the warnings says.
You can test a proper server function and a proper URL by using the URL in a webbrowser. The result should be a tile of the map. Or a some error message. HTH Oliver > Gesendet: Montag, 20.
