This error does not stop the code, how to handle this error? I am using below command with threaded = True
kws.connect(threaded = True)

Complete Error below:

raise ValueError("unknown bio failure")
builtins.ValueError: unknown bio failure

This seems to be an issue around the OpenSSL package. You can check more about the above exception here.

how to handle this, please provide any solution I don't know why it is happening. Moreover, It does come after some time, not immediately.

?

how to handle this, please provide any solution
kws.connect(threaded = True)

You have to forgo with thread ticker in Anaconda setup.

I am running my code in cmd, it doesn't have any link with Anaconda I guess
Then how should I run my code ?
Thanks

As per the above log, you seem to be running inside Anaconda env. Can you deactivate conda env and then run the code once?

Anjan

are you able to fix this @nikhilchawla

nikhilchawla

No, if you got any solution then let me know

As explained above, this is an issue with the Anaconda environment and is not related to the usage of Kiteconnect. Related link for a similar issue.
