Hi Upstox team,
I’m encountering frequent WebSocket disconnections with the following error:
sent 1011 (internal error) keepalive ping timeout; no close frame received
The client keeps reconnecting and resetting the message count, but the issue persists. I also noticed this warning in the logs:
Received FeedResponse with unexpected type: 2
Interestingly, after a few minutes, the WebSocket starts working again after reconnection, but the repeated disconnections are disrupting the flow.
Could you please check if there’s an issue on the server side?
I’m currently in the development phase of my algo app and using MCX data for building/testing, as it provides longer market hours.
Thanks!

Hi @SHUDHANSHU_41690975 can you confirm which version of websocket you are using v2 or v3?
@Ketan It is v3, and here is some log which might be helpful.
