Quick answer

A custom domain fails when DNS does not point at Netlify, a proxy intercepts traffic, or DNSSEC blocks validation. Check records with dig, then renew the certificate.

Most likely fix: Verify DNS

How to fix it

Try these in order — the most common fix is first.

  1. 1. Verify DNS

    1. Run dig +short yourdomain.com and dig +short www.yourdomain.com
    2. Run curl -sI http://yourdomain.com and look for server: Netlify
    3. Follow the values in Domain management > Options

  2. 2. Wait for TTL or flush caches

    1. Wait for the old TTL to expire
    2. Use Google Public DNS Flush Cache

  3. 3. Turn off proxying

    1. In Cloudflare set records to DNS only until the certificate is issued
    Did this fix it?
  4. 4. Disable DNSSEC

    1. Turn DNSSEC off at the registrar if using Netlify DNS, or use external DNS
    Did this fix it?
  5. 5. Remove the domain from the other site

    1. If it says domain already in use, remove it from the other site first
    Did this fix it?
  6. 6. Set both apex and www

    1. Add both in Domain management and point both at Netlify
    Did this fix it?

Symptoms

The domain shows another site, a DNS error, 'Check DNS configuration', or a certificate warning.

Why it happens

  • DNS records not pointing to Netlify
  • Old records cached until TTL expires
  • Cloudflare proxy in front of Netlify
  • DNSSEC enabled with Netlify DNS
  • Domain already assigned to another site
  • Apex works but www missing or vice versa
