Getting the Cloudflare 1010 Error – How Do I Fix This Access Denied Issue? or Cloudflare 1010 Error B

This error’s such a pain. Had it pop up when I was tweaking my site’s security settings.

Cloudflare 1010 can trigger if you’ve got aggressive rate limiting or firewall rules.

Check your Cloudflare dashboard under Security > WAF. Maybe a rule’s gone wild.

Also, clear your DNS cache (ipconfig /flushdns on Windows). Sounds dumb, but it’s helped me before.
