solved, but leaving this up for others to find. see How to change custom domain on Substack · Issue #473 · sw-yx/swyxdotio · GitHub for my stream of thought notes lol.

PLEASE help us help you by writing a good post!

we need to know your netlify site name. Example: gifted-antelope-58b104.netlify.app

this isn’t technically a Netlify site… it’s a domain managed by Netlify DNS (swyx.io, where the www. maps to scout-videos-51664) but what I am trying to do is redirect a subdomain (lspace.swyx.io) to my new Substack domain (latent.space) via Redirect.pizza.

  • DNS issues? Tell us the custom domain, tell us the error message! We can’t help if we don’t know your domain.

X-NF-REQUEST-ID is 01GVQ54JJJWJM3PZX6NKNC62E5, but it 404’s for some reason.
