Due to changes in the way Cesium is handling authentication and access to their terrain data, I've had to update the Cesium viewer to get it running again. This new release has been tested with both Cesium Ion viewer and FlightGear version 2019.1.1 as the viewer. I tested with Qt version 5.12.8, but whichever version you run make sure to add the additional Qt libraries as specified in the Wiki documentation on building QtJSBSim. The JSBSim version I tested with is built from source code downloaded 18 Apr 2021.
