@Moderator_2 add on more function like below

def _on_close(wsapp,code,reason):
      on_close(wsapp)

and add this function to sws object like below

sws._on_close=_on_close

Above lines of code will resolve the issue of error during close.

@Moderator_2 I placed the websocket python file locally and importing it. Now it's working fine. Thank you. Didn't really know why it worked? Any comments?

@Moderator_2 Hi this issue is not about having more than three connections. This issue comes even with only one connection with only one token subscribed. And this happens lot of time.
Not only that, even if you unsubscribe the token using sws.unsubscribe(correlation_id, mode, token_list) and sws.close_connection(), it doesn't close and gets resubscribed.

Hi @Manish-Choudhary

Apologies for delayed response.
Please reverify on the no of connection, we have limit of three connection Websocket smartAPI, if total connection per client count reached 3 all new connection will be blocked.

Thanks & Regards,
