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):

it was working properly 4 days before, but suddenly an issue with server. Can someone help me to troubleshoot this.

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, 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.
