SmartWebSocketV2 reconnect only returns one ticker data after disconnect — all other tickers stop updating

Ekraj

Hi all,

I’m using SmartAPI’s SmartWebSocketV2 to stream multiple NSE tickers and generate live signals using Order Book Imbalance (OBI) and Volume Imbalance.

Problem:

Initially, the WebSocket streams all tickers correctly.

After some time, I see repeated disconnects and reconnects:
example :

current subscription logic:

self.ws = SmartWebSocketV2(jwt_token, API_KEY, CLIENT_CODE, feed_token)
self.ws.on_open = self.on_open
self.ws.on_data = self.on_data
self.ws.on_error = self.on_error

def on_open(self, ws):
print(" WebSocket connected")
self.ws.subscribe("stream_1", 3, [{"exchangeType": 1, "tokens": tokens}])

i tried everything but it dosent fixed.
is there anything im missing or bug im not abel to catch.
