@rupurt Assuming that you're using self-signed certificates and have certificate validation enabled (rejectUnauthorized=true), we just published an update to the Python SDK (dev22) that should fix this error. Could you please give it a try and let us know?

See https://zowe-client-python-sdk.readthedocs.io/en/latest/usage/advanced.html for more details:

The Python SDK supports the commonly used environmental variables REQUESTS_CA_BUNDLE and CURL_CA_BUNDLE to provide a certificate chain.

Sweet. Yep, that is working nicely 🙏
