How do I disable Cloudflare on my iPad's connection to my website?

Disabling Cloudflare doesn't affect your iPad directly. Instead, you need to change your iPad's DNS settings to use your ISP's default DNS servers or another DNS provider. This will bypass Cloudflare's network. Alternatively, you can disable Cloudflare entirely by changing your domain's nameservers away from Cloudflare's nameservers in your domain registrar's control panel.
