Try the suggestions in this Community Tip to help you set up DNS records when you encounter the error “No A, AAAA or CNAME record found” on the DNS tab or “ERR NAME NOT RESOLVED” in the browser when you visit your site.
The error “No A, AAAA or CNAME record found” or “ERR_NAME_NOT_RESOLVED” means that you don’t have required entries in your DNS zone file at Cloudflare for the site to resolve properly. When you add a zone to Cloudflare, we scan and import your domain’s DNS records. The DNS scan goes through a dictionary of the most common DNS names and it queries the current name servers. If it gets a response, it adds the record. If the DNS records are unique or the domain is newly registered, our system may not detect the records and you’ll need to manually add them.
Quick Fix Ideas
A list of all the DNS records the system found is displayed on the DNS tab of the Cloudflare dashboard, including your subdomains. On that tab, you can decide which subdomains you want to enable Cloudflare or bypass Cloudflare . Some records, like MX, never go through Cloudflare (no cloud). Click the to turn it and the to turn it . If there are any additional records you’d like to add, you can add them on the DNS tab.
Due to the way DNS works, it’s not possible for us to import all of your records “as-is”. Instead, our scanning tool searches for the most common DNS records (several thousand) based on our production data. If that scan misses records, you’ll need to add them. If that happens, don’t panic, you can add them on the DNS tab and your host will be able to give you any details you need to enter.
If you have a newly registered a domain that you registered as no immediately added to Cloudflare, it is not uncommon to have no DNS records imported and you will need to manually create them. If you are not sure about records, you can get the appropriate records from your hosting account, and/or by contacting your hosting provider.
You can set-up subdomains by adding additional DNS records after configuring them on your web host, learn more.
Note that DNS changes you make will propagate to the CloudFlare DNS servers within 5 minutes, however global propagation of the DNS change can take up to 24 hours. During that time your old information will be in place.
- Address Mapping records (A)…The record that holds the IP address of a domain.
- IP Version 6 Address records (AAAA)…The AAAA record is similar to the A record, but it allows you to point the domain to an Ipv6 address.
- Canonical Name records (CNAME)…A CNAME (Canonical Name) forwards one domain or subdomain to another domain, does NOT provide an IP address.
- Mail exchanger record (MX)…Directs mail to an email server.
- TXT record…Lets an admin store text notes in the record.
