Causes
- a Cloudflare customer blocked traffic from your client or browser.
- Error 1006 also occurs in the Cloudflare Workers app under the Preview tab when a customer uses Zone Lockdown or any other Cloudflare security feature to block the Google Cloud Platform IPs that the Preview tab relies upon.
Fixes
Step 1
Request the website owner to investigate their Cloudflare security settings or whitelist your client IP address. Since the website owner blocked your request, Cloudflare support cannot override a customer’s security settings.
