**Log the last event received.** Instrument the stream loop to record the type of every event and print the last one before the close. Expected: you see where the cut happened, usually after content_block_delta events during a long generation, or right after an error event.

**Check for a mid-stream error event.** Look for an error event in the stream, for example an overloaded_error or an api_error sent after the response started. Success check: if an error event is present, the API did report the failure in-band; surface that error in your code instead of the generic stream-ended message, and retry with exponential backoff.

**Test the same request without your proxy in the path.** Run the identical streaming request from a direct connection, bypassing any reverse proxy, corporate gateway, or serverless edge layer. Expected: if the direct stream reaches message_stop, an idle timeout or response buffering setting in the middle layer is closing long-lived SSE connections; raise its idle timeout and disable response buffering for the streaming route.

**Raise the client timeout and keep retries on.** Use the SDK default timeout or a longer one for streaming calls, not a short REST-style timeout, and leave the SDK max retries enabled so transient closes are retried automatically. Success check: a deliberately long generation completes and the stream ends with a message_delta carrying the stop reason, followed by message_stop.

**Handle a cut stream as a failed request.** In your own stream consumer, raise or return an error when the connection closes before message_stop, and retry the full request with backoff and jitter rather than appending to the partial text. Success check: a simulated mid-stream disconnect produces one clean retried response, never a half answer presented as complete.
