GitHub Notifications on GitHub Enterprise

Writing a new post for my blog about getting GitHub Notifications up and running for a GitHub Enterprise instance. While writing this post, I encountered a problem at the very end, involving the GHE API returning an error to my browser after trying to asynchronously load the repository list and the notifications.

@bkeepers, have any ideas about what might be causing this? Here's the message:

```json
{
  "message": "Maximum number of login attempts exceeded"
}
```

And a fun screenshot of my screen:
