I am facing a server connection issue while running the Auto segmentation tool on Nvidia.  
I am getting the following error:  
Traceback (most recent call last):  
File “C:/ProgramData/NA-MIC/Slicer 5.2.2/NA-MIC/Extensions-31382/NvidiaAIAssistedAnnotation/lib/Slicer-5.2/qt-scripted-modules/SegmentEditorNvidiaAIAALib/SegmentEditorEffect.py”, line 198, in fetchAIAAModels

Hi,  
this server for NVIDIA AIAA was hosted by the Slicer team, I think it is probably switched off by now. NVIDIA AIAA is no longer recommended. The successor tool is [MONAI Label](https://github.com/Project-MONAI/MONAILabel), and there is an accompanying plugin for 3D Slicer, which can be installed via the Extension Manager. For more details on the module, visit [here](https://github.com/Project-MONAI/MONAILabel/tree/main/plugins/slicer).
