Cloudflare Error 1000: DNS Points to Prohibited IP

Cloudflare is a popular content delivery network (CDN) that provides website security, performance, and reliability services. However, sometimes users may encounter errors while accessing websites that use Cloudflare. One such error is Error 1000: DNS Points to Prohibited IP. In this article, we will discuss what this error means and how to solve it.

What is Cloudflare Error 1000?

Cloudflare Error 1000 occurs when a website’s DNS points to a prohibited IP address. This means that the IP address associated with the website is not allowed by Cloudflare. As a result, Cloudflare cannot proxy the traffic to the website, and users see the Error 1000 message.

Common Causes of Cloudflare Error 1000

There are several reasons why a website’s DNS may point to a prohibited IP address. Some of the common causes of Cloudflare Error 1000 are:

• A DNS record in your Cloudflare DNS app points to one of Cloudflare’s IP addresses.
• An incorrect target is specified for a CNAME record in your Cloudflare DNS app.
• Your domain is not on Cloudflare but has a CNAME that refers to a Cloudflare domain.
• There is a reverse proxy at your origin that sends the request back through the Cloudflare proxy.

How to Solve Cloudflare Error 1000

If you encounter Cloudflare Error 1000 while accessing a website, there are a few things you can do to solve the issue. Here are some steps you can take:

1. Check your Cloudflare DNS settings: Verify that your Cloudflare DNS settings include an A record that points to a valid IP address that resolves via a DNS lookup tool. If an A record within your Cloudflare DNS app points to a Cloudflare IP address, update the IP address to your origin web server IP address.
2. Check your CNAME records: For a CNAME record pointing to a different domain, ensure that the target domain resolves via a DNS lookup tool. An incorrect target is specified for a CNAME record in your Cloudflare DNS app.
3. Check your reverse proxy settings: If there is a reverse proxy at your origin that sends the request back through the Cloudflare proxy, contact your hosting provider or site administrator to configure an HTTP redirect at your origin.
4. Contact Cloudflare support: If the issue persists beyond 5 minutes, contact Cloudflare support for further assistance.
