DNS-NO-WWW
www does not resolve
What it means
Visitors and links still use the www prefix. If it does not resolve, they see an error instead of your site.
How to fix it
- 1Add a www CNAME to the apex, or an A/AAAA record matching it, and redirect one form to the other in the web server.
Re-check after the change
DNS changes can take up to the record's TTL to be seen; use Re-run on the result page to bypass our 10-minute cache.
