"Premature close" is a transient network/stream error that occurs when the connection between Continue and your model provider is interrupted mid-stream. We don't automatically retry these errors because they occur mid-stream and retrying could cause corrupted or duplicated output.

If you continue to experience this issue frequently or in specific reproducible scenarios, please open a new issue with details (provider, model, OS, and steps to reproduce) so we can investigate further.
