With split-DNS, you have different DNS records for internal and external users. Ensure your internal DNS records are correctly configured and accessible only from your internal network. Verify that Cloudflare's DNS records are correctly pointing to your public DNS servers. Use `dig` or `nslookup` from both internal and external networks to confirm that the correct DNS servers are being used for each location. Pay close attention to any caching issues that might be affecting resolution.
