  1. Missing A DNS Record: Cloudflare’s DNS configuration lacks an A record pointing to your server’s IP address.
  2. Unresolved CNAME Record: A CNAME record pointing to an external domain that cannot be resolved.
  3. Load Balancer Issues: Unresolvable origin hostnames in Cloudflare’s load balancer pools.

Step-by-Step Guide to Fix Cloudflare Error 1016

Let’s learn from our detailed instructions on how to identify the root cause of the problem, such as checking the DNS settings, verifying the Cloudflare configuration, and ensuring that the origin web server is correctly set up. However, by following our guide, users can effectively fix the Cloudflare Error 1016 and ensure their website’s smooth operation. Also, it’s a must-read for anyone seeking to maintain optimal website performance and uptime.

Step 1: Verify Cloudflare DNS Settings

The first step is to ensure your Cloudflare DNS settings are correctly configured.

  1. Log into your Cloudflare account and select your website.
  2. Navigate to the DNS tab.
  3. Check the A Record:
    • Ensure there is an A record that points to your server’s IP address.
    • If missing, add a new A record with your domain name and IP address.
  4. Check the CNAME Record:
    • Ensure any CNAME records correctly point to their respective targets.
    • If a CNAME points to an external domain, verify that the target domain resolves correctly.

Step 2: Check CNAME Resolution

If your DNS settings seem correct, the next step is to ensure your CNAME records are resolving properly.

  1. Use the dig command:
    • Open your terminal or command prompt.
    • Type dig subdomain.example.com to check DNS resolution.
    • Use dig +trace subdomain.example.com for detailed trace information.
  2. Use the nslookup command:
    • Type nslookup subdomain.example.com to check DNS resolution.
    • For more details, use nslookup subdomain.example.com 1.1.1.1.

If these tools indicate issues with DNS resolution, you may need to adjust your DNS settings or consult with your DNS provider.

Step 3: Ensure Server Availability

Cloudflare Error 1016 can also occur if your server is not available.

  1. Check Server Status:
    • Ensure your server is online and reachable.
    • Verify there are no firewall rules or security settings blocking Cloudflare’s IP addresses.
  2. Verify IP Address:
    • Ensure the IP address in your DNS settings matches your server’s current IP address.

    • Ensure all pools have resolvable and active origin servers.
  3. Update Origin Hostnames:
    • Replace any unresolvable hostnames with correct, active ones.

Step 5: Contact Cloudflare Support

If the above steps do not resolve the issue, you may need to seek professional help.
