    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.

    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?
