Hi @b.ashok.amrutkar ,
According to your stack trace it seems that the main cause is:
Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)'))
This indicates that there is a problem with an SSL certificate on your computer. There was one user that reported the same issue a while ago but for a different Python utility. Please check our answer:
