What are best practices to prevent the Cloudflare 526 error

To prevent a Cloudflare 526 error: 1) Always use a valid, publicly trusted SSL certificate from a reputable Certificate Authority on your origin server. 2) Implement automated renewal for your SSL certificates to prevent expiration. 3) Ensure your server's SSL configuration is correct, including the full certificate chain and proper intermediate certificates. 4) Regularly monitor your SSL certificate's health and expiration dates using online tools or server-side alerts. 5) Maintain your Cloudflare SSL/TLS encryption mode at 'Full (strict)' but be proactive in resolving any origin certificate issues immediately. 6) Configure your web server to use modern, secure, and widely supported cipher suites and TLS protocols.
