Loading HTTP resources on HTTPS pages. Fix: Update all URLs to HTTPS or use protocol-relative URLs.
Certificate Expired
Set up auto-renewal (Let's Encrypt renews every 90 days automatically via certbot).
Name Mismatch
Certificate doesn't match domain. Ensure cert covers both example.com and www.example.com.
Chain Incomplete
Missing intermediate certificates. Use fullchain.pem instead of just cert.pem.
HTTP to HTTPS Redirect
Add 301 redirect: RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
