    @Ashok

    what I meant was whenever this happened I stopped the script and restarted it. this is what I meant by happened three times..

    were you still getting the data even when it was printing HeartBeats Failed ??

    @rajanprabu I was getting the data even when heartbeat failed. So I think there is issue with the heartbeat logic.

    @rajanprabu Looks like during print of HB failed, no data, but once it reconnects, data starts to flow.
    but there is a pause between hb failed and reconnect. also I could see lot of reconnects happening.
    In below snippet, all those logs with userid are reconnect I suppose.

    @admin I'm also facing this issue, WebSocket connection closes at random times. around 11AM or around 1:30 PM or around 2:30 PM. sometimes it stops multiple times a day. It happens almost daily.
