Troubleshooting Database

Cause: Certificate Expired or System Clock wrong.
Fix: Renew certificate immediately or sync your computer clock.

Cause: Server using SSLv3/TLS 1.0.
Fix: Update Nginx/Apache config to support TLS 1.2 or TLS 1.3.

Cause: Domain mismatch (e.g. www.site.com vs site.com).
Fix: Reissue certificate to include both variations (SAN).

Cause: Cloudflare "Full (Strict)" mode failed.
Fix: Valid SSL required on Origin. Switch Cloudflare to "Full" (Not Strict) temporarily.
