Hi Luke,
It’s exactly the issue I’m having… the root domain is working fine (Stadtharmonie.ch) but not the subdomain www.stadtharmonie.ch.
I am quite confused now on how to handle this, on the one hand I read in your documentation: “If you assign an apex domain or a www subdomain to your site, Netlify will automatically add both the apex domain and the www subdomain.” On the other hand, under domain settings, it tells me to check DNS configuration and add the CNAME, which should be pointing to stadtharmonie.netlify.com. I tried doing exactly this, but then got error messages saying the website wasn’t secure when I tried going to www.stadtharmonie.ch.
Thanks for any insights, as I am very confused at this point how to solve the issue. Otherwise: absolutely loving Netlify and Netlify CMS! Cheers,
Rosanne
