Deepgram STT: deepgram connection closed unexpectedly

[sanchitcloud16]

We are using deepgram STT in voice call using livekit framework. Frequently we get below error from the deepgram websocket API. We are not able to find any issue at our end and it looks like deepgram is rejecting connection. Can anyone let us know what might be the issue here
