I’m pretty sure I have everything but it gives me a 404
That is indeed weird. Maybe a CM can check this out?
Is the repository that you’re working with a private repository? I’m not seeing any public repositories on your profile.
Edit: I did find this repository that you have committed to: https://github.com/nnmg-studios/nnmgstudios.github.io . Is this the one that you’re trying to work with? If so, it’s a different URL than what you have in your OP. If you’re trying to make an organization pages site, you’ll need to rename that repository to nnmg-studios.github.io to be able to use that URL.
Hope that helps!
