Websocket ticks stop after disconnection and reconnection

algonauts

Hi,
I am using pykiteconnect and had a problem with reconnection after the websocket disconnection.
The websocket connection with my app got disconnected with code 1006 and it was reconnected after 3 seconds. But I did not receive ticks after the reconnection. Pykiteconnect does resubscribe to the tokens I believe still I did not receive ticks. Do I have to resubscribe to the tokens for the ticks? Or there could be some another issue?

@algonauts,
Kite Ticker will return a cached tick after reconnection. Since a subscribe message is sent for all the tokens.

Hi @sujith, we too are facing a similar issue for the past couple of days.
Websocket reconnects but the process doesn't get any tick updates. It was working fine till now, a few disconnects and it always used to resume fine.
But this week it just reconnects without any tick updates.

FYI, I'm not resubscribing tokens in case of reconnection, and no changes have been made recently.
Is there any particular case when we should resubscribe?

@gauravmane,
You don't have to subscribe again after disconnect. The Kite Connect library takes care of subscribing.
Let me check if we can reproduce this.

We tried re-producing, but re-connection is happening all fine.

If re-connection has happen successfully,token should be re-subscribed too. Can you paste your Websocket code? We will take look at it.
