Answer 1

The cert parameter is for client-side authentication. If you wanted to prove your identity to the server. If this was the problem you would get an error on the server.

What you need is server-side authentication. The server has to prove it's identity. As your are connecting to an internal server requests doesn't have this server certificate in it's supplied bundle and therefore can't confirm the servers identity. You have to supply requests with your internal CA-bundle. To do this you have to extract it from your browser first.

From the docs:

You can also pass "verify" the path to a "CA_BUNDLE" file for private certs.
You can also set the "REQUESTS_CA_BUNDLE" environment variable.

Chrome (short version):

• Put this in your URL-bar chrome://settings/certificates
• Choose tab "Authorities"
• Find your internal CA and click export
• Best format is "Base64 encoded certificate chain"
• save to a location where you will find it again
• now you can use `request.get(url, verify=)

You can also visit the certificate manager by:

(Steps for chrome, quite similar for other browsers)

• Go to settings
• Click "Show advanced settings" at the bottom
• HTTPS/SSL -> "Manage Certificates"
• See above
