Custom Domain Error Just appeared

Shopify Discussion

Topic summary

Shopify store owners are receiving unexpected “Custom Domain Error” notifications about wildcard DNS records, despite not making any recent domain changes. Many affected users have had their stores running for 5-10+ years with domains through providers like GoDaddy and WordPress.

The Core Issue:

  • Error messages claim domains have wildcard records pointing to Shopify or CNAME records not properly configured
  • Some users report their www subdomain CNAME is being flagged, with Shopify requesting it point to shops.myshopify.com
  • Current DNS settings (like A records pointing to 23.227.38.32) differ from what Shopify now recommends

Shopify’s Response:

  • Official representative clarified this is NOT an actual error or indication of unauthorized changes
  • Instead, it’s a proactive notification about DNS best practices for security
  • Shopify recommends: removing wildcard DNS records, ensuring each domain has specific DNS entries, and pointing CNAME records to shops.myshopify.com
  • No recent changes were made to Shopify’s IP addresses or CNAME requirements

User Concerns:

  • Confusion about why this is labeled an “error” if it’s just a best practice recommendation
  • Hesitation to modify long-standing, functional configurations
  • Some users cannot easily edit DNS records due to provider-managed templates or restrictions

Shopify advises contacting domain providers for assistance with DNS adjustments.

Hi, @Italia-Straps .

My apologies for any confusion about this. To clarify, there is no concern regarding access issues. The request to remove wildcard records is in the interest of security both for your information and our platform.

The only records you need to connect your domain to Shopify are the A record and CNAME record outlined in this guide: Connect your third-party domain to Shopify manually.
