Hello Andras,

**Could you please help me with this error message when using the Nvidia Segmentation extension:**

```auto

There is an issue with the free server that we have set up that we expect to resolve within a few weeks ([Slicer default server needs an upgrade to latest version of AIAA/Clara · Issue #62 · NVIDIA/ai-assisted-annotation-client · GitHub](https://github.com/NVIDIA/ai-assisted-annotation-client/issues/62)). You can either wait for that fix or set up your own Clara server.
