The error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed
usually originates as a result of not having up-to date certificates or as a result of some internal firewall interceptions and not as a result of Cognite's SDK/API.
I would suggest initially checking if there are any internal certificates that are blocking external requests and possibly try updating your python certifi package which could also help resolve the issue.
If that doesn’t work can you try using a diffrent network and check?
