I have just set up the cloudflare on site. And I have already changed nameservers on my domain provider. But I still see this in speed check section:
The Speed test could not run. example.com returned a status 404. Try the options below to fix the issue.
1 Review the configuration between your origin server and Cloudflare and ensure that the origin resolves requests successfully
2 Review any existing Firewall Rules applied to your website which may be blocking access to ‘Known Bots’
