Let's Encrypt renewal fails: "xn--krderheimen-hgb.no doesn't appear to be served by Netlify"

Hi,

My site has been working fine since April, but on July 21 the Let’s Encrypt certificate expired and my custom domain stopped working.

Netlify site name:
kroderheimen.netlify.app

Custom domains:

  • krøderheimen.no (xn--krderheimen-hgb.no) – Primary domain
  • www.krøderheimen.no
  • kroderheimen.no
  • www.kroderheimen.no

Error when renewing the certificate:

xn--krderheimen-hgb.no doesn't appear to be served by Netlify

We can’t provision a certificate until your DNS configuration is pointing at the Netlify servers and the changes have propagated.

Current status:

  • The Netlify subdomain works: https://kroderheimen.netlify.app

  • DNS is hosted at Domeneshop.
    Nameservers:
    ns1.hyp.net
    ns2.hyp.net
    ns3.hyp.net
    DNS records are:
    A → 75.2.60.1
    A → 75.2.60.5
    CNAME www → kroderheimen.netlify.app

    • External DNS lookups confirm the records are correct.

    In Netlify, all custom domains are green under Domain management.

  • However, the HTTPS section still says:

    “xn–krderheimen-hgb.no doesn’t appear to be served by Netlify”

    The certificate expired on July 21, and clicking Renew certificate always fails with the same error.

I haven’t changed my DNS configuration before this happened.

Could someone please check whether the SSL provisioning or domain verification for this site is stuck on Netlify’s side?

Thank you!
