step 4: use a custom ca bundle

if you are working with a self-signed certificate or an internal ca, you can provide the path to a custom ca bundle:

step 5: update python and libraries

sometimes, updating python and libraries can resolve compatibility issues related to ssl certificates. ensure you are using a supported version of python and the `requests` library.
