How do I ensure my website shows a valid certificate on iOS through Cloudflare?

To ensure your website shows a valid certificate on iOS through Cloudflare, ensure that your domain is active in Cloudflare and proxied. In your Cloudflare SSL/TLS settings, set the mode to 'Full' or 'Full (Strict)'. If using 'Full (Strict)', make sure you have a valid SSL certificate installed on your origin server. Cloudflare will then issue its Universal SSL certificate for your domain, which iOS devices will automatically trust, displaying the padlock icon and indicating a secure connection.
