Change the file format from .txt to .pem. Once all certificates have been downloaded and bundle up, run this code: import requests. url = "https://site-with-self-signed-certificate.org". # cert_path is the chain PEM file download or bundle together for the url above. cert_path = "path/to/bundle.chain.cert.pem".
