DNS points to prohibited IP

What happened?

You’ve requested a page on a website ( that is on the Cloudflare network. Unfortunately, it is resolving to an IP address that is creating a conflict within Cloudflare’s system.

What can I do?

If you are the owner of this website:
you should login to Cloudflare and change the DNS A records for to resolve to a different IP address.


Thank you for asking.

The error is correct as far as I am afraid your are putting Cloudflare IP instead of your hosting / origin server IP address into the Content field for both A and AAAA records.

You should get provided the IP address(es) from your hosting provider.

However, since using Workers on a defined route path like*, may I ask if you’ve tried pointing to a temporary IP address for that particular proxied :orange: hostname (naked domain and/or www) like :thinking:

Hi @fritex thanks for reaching out with awesome helpful info. The issue was resolved in the end by modifying the CF Worker script. There was issues in the script and modified it see here: Using Cloudflare workers to redirect multiple URLS - Developers / Workers - Cloudflare Community

But as FYI you can indeed use CF workers without needing any A or CNAME records specified. You can add them direct to the Worker itself (To do so you must remove any A or CNAME records for the domain first then add them directly into CF workers) see screen shot and i have marked out confidential client data. hope this helps you as well.
