Thanks @maciejg - I followed the steps and deleted the certificate from both _Trusted Root Certification Authorities_ and _Third Party Root Certification Authorities_ . but look like windows 10 just automatically reinstalls the “DST Root CA X3” certificates.

I also looked at another post on this [SSLCertVerificationError using python SDK - #5 by kellytmcnallan](https://forum.alpaca.markets/t/sslcertverificationerror-using-python-sdk/6999/5)

Where they suggested simply deleting the “DST Root CA X3” from the pem file (which is a text file that python uses for storing certificates). Got the location of the pem file by running the following commands.

import certifi  
print(certifi.where())

I still get the same certificate verify failed error. Any thoughts?
