can anyone help me with some certificate issues..? I'm using Landscape, and trying to use the python API, but I get a CA mismatch, but I've downloaded the .pem, and pointed the script to the location of the .pem.. I get a 403, and error: Message: {"message": "The request signature we calculated does not match the signature you provided. Check your key and signing method.", "error": "SignatureDoesNotMatch"}

Trying to do some testing on a LAN without a CA, the script is being run on the server that Landscape is being run on. Here is the contents of my python script, obviously with critical information changed.
