`shiffman.net` redirect to `thecodingtrain.com` not working with `https` protocol

Adding it here so there's more visibility. I feel like we've discussed this on Discord before but it hasn't been corrected.

The http:// redirection works, but with https:// is just a generic Squarespace landing page.

Because of the HSTS response header, it's easy to get in a state were we can never really go back to http:// without manually purging the HSTS policy for the domain in the browser. Modern browsers also have an HTTPS-only mode available and would never land on the non-secure version of the URL to begin with.

I don't know how the current implementation works, but can this not simply be handled by their domain forwarding service? https://support.squarespace.com/hc/en-us/articles/214767107-Forwarding-a-Squarespace-domain

As an alternative, you could just point the DNS to a Netlify or Cloudflare account and handle the redirection logic there instead.
