GH Pages 404s on repo name but not path

So I have a repo named angles-n-daemons.github.io which I have done intentionally to setup a github pages site.

I have the default configuration set, and everything points to the site being available at https://angles-n-daemons.github.io however, when I try to navigate there I get a 404.

The annoying or troubling thing is, when I navigate to the path of the repo - it works ie:
https://angles-n-daemons.github.io/angles-n-daemons.github.io

Does anyone have the slightest idea what could be going on here?

hmmm…this randomly started working like an hour later
