_main__:1: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography. The next release of cryptography will remove support for Python 3.6.

I have latest versions installed. The starnge thing here is its saying 2.20 is installed which is not latest.
I am using below versions:
Current versions:

pip show requests
requests: 2.20.0
pip show requests-toolbelt
requests-toolbelt: 1.0.0
pip show pyopenssl
pyopenssl:23.2.0
pip show cryptography
cryptography:40.0.2

I suspect we're not able to find the PyOpenSSL Context object

https://github.com/requests/toolbelt/blob/master/requests_toolbelt/adapters/x509.py#L129-L137

Our exception message should be clarified probably but your system still seems to not have what we need for us to support the X509 adapter properly
