Creating a hook for a private repository, login produces a GitHub 404 page

[NameOfTheDragon]

When attempting to create a webhook for a project, the plugin prompts for GitHub login. It opens a browser window pointed to https://github.com/login/oauth/authorize?client_id=[removed]&cope=public_repo%2Crepo%2Crepo%3Astatus%2Cwrite%3Arepo_hook&state=[removed]

This page produces a GitHib 404 error.

Notably, the repository is a private repository and the URL implies it should be looking for a public repo.
