What is right in following:

or
sws.subscribe(action=0, correlation_id, mode)
or
sws.subscribe(action=0, mode, token_list1)
or
sws.unsubscribe(action=0, correlation_id, mode, token_list1)
or
sws.unsubscribe(action=0, correlation_id, mode, )

or
sws.unsubscribe(action=0, correlation_id, token_list1)

or
sws.unsubscribe( correlation_id, mode, token_list1)

or
sws.unsubscribe(action, mode, token_list1)

@Moderator_2

check Nse fobhacopy with your (daily) historical data.

May be issue with internet connection connectivity if ok then check your internet connection is public connection or private connection, if public connection, change to private connection
