# Error 1010

> How to resolve Cloudflare Error 1010 and DNS proxying issues.

When configuring your domain DNS with Cloudflare, you may encounter **Error 1010: Access Denied** or domain verification failures.

## Cause of Error 1010

This error typically occurs when:

1. **Cloudflare Proxy (Orange Cloud) is enabled**: Mailofly requires direct DNS resolution for MX, TXT (DKIM/SPF), and CNAME verification. If Cloudflare's proxy is turned on, Cloudflare returns Cloudflare proxy IPs instead of Mailofly's mail server target, blocking verification.
2. **Cloudflare Security / WAF rules**: Overly aggressive WAF rules or Bot Fight Mode may block automated verification pings.

## How to Fix

<Steps>
  <Step title="Disable Cloudflare Proxy">
    In your Cloudflare dashboard, locate all DNS records created for Mailofly (DKIM, SPF, MX, and Return-Path).

    Ensure the **Proxy status** is set to **DNS only** (gray cloud icon), **not** Proxied (orange cloud icon).
  </Step>

  <Step title="Wait for TTL Cache Expiration">
    DNS propagation through Cloudflare usually takes 2 to 5 minutes once set to "DNS only".
  </Step>

  <Step title="Re-verify in Mailofly">
    Navigate to **Domains** in your Mailofly dashboard and click **Verify DNS Records**.
  </Step>
</Steps>
