@Myles Gmail doesn't use that kind of authentication, so this will never work (Google has spent a good deal of time making sure Gmail can't be accessed this way).

Sorry I didn't spot you were trying to access the atom feed. I've tested it and it works so I'm not sure what error you get.  I imagine the most likely issue is you cannot use (neither would you want to) your normal password: make sure you have 2-step verification enabled and create an app password.
