I get a 404 currently, fwiw.

Fixed! Pages drops the custom domain whenever I push right now, have been putting off debugging it - apologies

If I understand the issue correctly, you just need a file called CNAME in the root of your repo containing your custom domain, like this: https://github.com/justusthane/justusthane.github.io/blob/ma...

Thanks! Unfortunately, I've somehow fallen off the paved road :) https://github.com/ramimac/wiki/blob/main/CNAME

GH Pages is particular about how your apex and www records are set up. I believe you need apex A records pointing to

185.199.108.153 185.199.109.153 185.199.110.153 185.199.111.153

which you already have. Your CNAME record at www.rami.wiki needs to point to "ramimac.github.io/wiki", and your CNAME file in the root of your repo needs to contain "www.rami.wiki" (www is necessary).

At this point, https://rami.wiki should automatically redirect to https://www.rami.wiki.

At least, that's more or less how mine is set up and it works for me :) I had the same issue as you until I got that all straightened out.
