How do I set up automatic SSL renewal with Let's Encrypt on HostingRaja's cPanel without it breaking my site?

Hi folks, I've been using HostingRaja's shared hosting for my small e-commerce site, and the free SSL via cPanel is great, but the certs expire every 90 days and I keep forgetting to renew manually—last time it caused a brief downtime. Is there a reliable way to automate Let's Encrypt renewals through their panel or a cron job? Do I need to tweak the .htaccess or add any specific flags to avoid conflicts with their Cloudflare integration? Any step-by-step that worked for you on their servers? Thanks a ton! golf hit
