Error 1002: DNS points to Prohibited IP

This error indicates that a Cloudflare DNS record points to a prohibited IP, preventing proper domain resolution.

Common causes

  • 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.

Resolution

Update your Cloudflare A or CNAME record to point to your origin IP address instead of a Cloudflare IP address:

  1. Contact your hosting provider to confirm your origin IP address or CNAME record target.

  2. In the Cloudflare dashboard, go to the Records page.

    Go to Records ↗
  3. Select the domain that generates error 1002.

  4. Select the DNS app.

  5. Select Value for the A record to update.

  6. Update the A record.

To ensure your origin web server does not proxy its own requests through Cloudflare, configure your origin webserver to resolve your Cloudflare domain to:

  • The internal NAT'd IP address, or
  • The public IP address of the origin web server.

Error 1002: Restricted

This error indicates that the domain resolves to a restricted or disallowed IP address.

Common cause

The Cloudflare domain resolves to a local or disallowed IP address or an IP address not associated with the domain.

Resolution

If you own the website:

  1. Confirm your origin web server IP addresses with your hosting provider,
  2. Log in to your Cloudflare account, and
  3. Update the A records in the Cloudflare DNS app to the IP address confirmed by your hosting provider.
