Cloudflare is one of the most popular DDoS protection platforms around at the moment and offers a bunch of other tools that help keep your sites up and running without hiccups. That said, it isn’t immune to the occasional bug or glitch that can ruin the user experience.
In this article, we’re talking about Cloudflare error 1016, its causes and what you can do to fix the problem.
What causes this error?
The error is generally triggered when Cloudflare can’t connect to your origin server because of DNS issues. The error code 1016 specifically indicates that the Cloudflare Anycast address cannot find the DNS record otherwise specified in the DNS records section of your account. Other common causes include:
- Missing DNS A record specifying the origin IP address.
- Missing CNAME record.
- Origin host name is unresolvable.

How to fix this?
Here are four fixes you can try out.
Check your origin domain
The first thing you need to do is make sure your origin domain’s hostname and IP address are resolving. Check with the domain registrar to see if it’s still active and if it is, crosscheck the IP address with your Cloudflare settings to ensure it’s pinging the right domain.

Add a valid A or CNAME record
Next up, check to see if a valid A or CNAME record exists in your Cloudflare dashboard pointing towards the origin domain. Alternatively, you can also check your CNAME record log to see any potential errors and rule them out.
Add a load balancer
Adding a load balancer often helps resolve any DNS issues you might be facing. The error code 1016 itself can show up from time to time if the origin host names in your Cloudflare Load Balancer default, region and fallback pools don’t resolve.
To fix this, use a fallback pool configured with your origin IP address as a backup in case other pools can’t resolve. This ensures that even if any protective services or domains aren’t working, your original domain can still be resolved by a browser.
Contact Cloudflare support
If nothing else works, the best option is to contact Cloudflare support and have them fix the problem for you. Alternatively, you can ask a question on Cloudflare’s community forum to see if someone experienced the same problems as you before and the steps they took to fix them.
