Failed to use Nvidia Annotation

hi everyone, anyone know how to solve this problem

Failed to fetch models from remote server. Make sure server address is correct and <server_uri>/v1/models is accessible in browser

It means that the segmentation server is unavailable. Have you set up your own server or using the default Slicer segmentation server?

Using default. How to setup my own server sir? Please help me

The default server is available now, but if you want to set up your own then follow the instructions here.
