When running dotnet build the build fails while attempting to download a model from Hugging Face. The error indicates the SSL connection could not be established and the transport connection was closed by the remote host.

Hypothesis
The file onnx/model_quantized.onnx at the URL above may have been moved, removed, or the Hugging Face path changed. As a result the build-target that attempts to download the file fails with an SSL/connection error.

Suggested next steps / possible fixes

• Verify whether the model exists at the Hugging Face URL and update the URL in the NuGet package/targets if it changed.
• Consider bundling a tested model asset with the package or providing a more reliable host or retry/backoff logic in SmartComponents.LocalEmbeddings.targets.
• If the model was intentionally removed, update package documentation and targets to reflect the new location or provide guidance for users to obtain the model manually.

Additional context

• Reported by user when building locally on Windows (exact output included above).
