Cloudflare settings

What every button in the Cloudflare settings does

My domains → domain → Cloudflare settings. Every domain has its own Cloudflare account: the email, password, and 2FA are on the domain card while it uses Cloudflare NS.

Do not share the Cloudflare account details: they give access to DNS and the website.

SSL mode

  • Full (strict) – the server has a valid certificate. The best option for a live website.
  • Full – the server has a self-signed certificate. Set after purchase.
  • Flexible – the server has no HTTPS. Temporary only: an HTTPS redirect on the server causes an endless loop.
  • Off – HTTPS is off.

More: Cloudflare docs.

DDoS protection

  • Off – almost no checks.
  • Low and Medium – normal operation. Medium is set after purchase.
  • High – stricter checks, some visitors see a challenge.
  • Under Attack – only during an attack: every visitor goes through a check.

Security rules

Up to 5 rules per domain. Create rule → name → expression → action.

  • Expression – the condition for matching requests, like the "When incoming requests match" field in Cloudflare. For example: (ip.src.country ne "US").
  • Block – the request is rejected.
  • Managed Challenge – Cloudflare picks the check itself.
  • JS Challenge – a browser check for a few seconds.
  • Interactive Challenge – the visitor passes the check manually.
  • Skip – other rules do not apply to these requests.

A rule can be edited, disabled, or deleted.

Redirects

Add → send a domain or a link.

  • Domain (target.com) – the path is kept: example.com/page opens target.com/page.
  • Link with a path (https://target.com/landing) – every page leads to it.
  • Code and scope – 301, works for the domain and all subdomains. Without a scheme the bot adds https://.
  • Remove – delete the redirect.

Purge cache

Clears the whole Cloudflare cache at once, with no confirmation. Use it when the server has a new version of the website but visitors still see the old one. DNS cache is not affected.

Hosting

A static website without your own server: send a .zip archive up to 20 MB with index.html at the root. The bot deploys it to Cloudflare Pages, connects it to the domain, and notifies you in a few minutes.

Third-party NS

With someone else's NS, the Cloudflare settings in the bot do not apply. Open any section and tap Link: the bot moves the NS back to Cloudflare.

Errors 521, 522, 525, 526: Domain does not work.
