The robots.txt rule
To block it:
User-agent: CCBot Disallow: /
To allow it explicitly:
User-agent: CCBot Allow: /
A server or CDN can still refuse the crawler when robots.txt allows it. That is why the checker fetches as the crawler as well as reading the file.

Check your own site
The free checker runs the same probe on any URL: robots.txt resolved for every AI crawler, then a live fetch as each one, so a CDN or firewall block shows up even when robots.txt looks fine.
