since some weeks I can not load WMS-Layers from the Nasa-Server (or any other). I already reinstalled WWT on different machines with different Windows (10 and 8), but the problem still exists.
The server adress I use is http://svs.gsfc.nasa.gov/cgi-bin/wms
Everytime I press "Get Layers" in the WMS-Layer-window the the download-progress-window pop up, but then there is no progress and the window closes after a second. Under "Layer and Styles" there are no layers listed and I can't choose
