Cloudflare SSL modes

Cloudflare offers several SSL modes that control how traffic is encrypted between your visitors, Cloudflare, and your server.

SSL modes explained

  • Off — No SSL. Not recommended.
  • Flexible — HTTPS between visitor and Cloudflare only. HTTP between Cloudflare and your server. Avoid this if possible.
  • Full — HTTPS everywhere, but doesn't verify your server's certificate. Fine for self-signed certs.
  • Full (Strict) — HTTPS everywhere with a valid certificate. Most secure. Recommended.

Use Full (Strict). This requires a valid SSL certificate on your server. Our Let's Encrypt certificates (installed via Plesk) are fully trusted by Cloudflare.

Fixing redirect loops

If your site shows a redirect loop (ERR_TOO_MANY_REDIRECTS), the SSL mode is likely wrong. Switch from Flexible to Full or Full (Strict) in Cloudflare → SSL/TLS.
