## TL;DR

Upgrade to v3.1.8 or later for the improved shutdown handling, and catch on_error for abnormal terminations since on_close only fires on clean shutdown. Fixes landed in v3.1.5/v3.1.8 improved exception handling; the recommended cleanup is to call finish() then create a new client.

## Steps

1. If Deepgram live streaming closes with 1011, check that you are sending audio or a keepalive at least every 12 seconds, otherwise the platform drops the connection by design. Also verify your audio encoding matches the encoding value you declared.
