301 redirect not working - domain I am redirecting from goes to a 404 instead of the redirected domain

I am having issues redirecting the .netlify sub domain to the primary domain. Here’s what I’m using:

https://seamlesslygutters.netlify.com https://seamlesslygutters.com 301!
https://seamlesslygutters.netlify.com/* https://seamlesslygutters.com/:splat 301!

But when I load the .netlify domain instead of redirecting to the primary domain it goes to a 404. What’s happening?

Here’s the github if you wanna play with it
