🛑 Troubleshooting: Firewall Errors
Understand why certain domains block analysis tools and what the red firewall warning means.
🛡️ Resolving Scraper Blocks
If you run an analysis (especially inside the Technical Site Auditor or AI Readiness tools) and receive a red warning panel, the target website is actively hiding its structure behind a protective security layer.
Why does this occur? Systems like Cloudflare or corporate hosting proxies protect sites from online attacks by blocking *all automated crawlers* that don't match standard white-listed browser tokens.
When RankAnvil attempts to access the page to count heading tags or locate broken code links, the security system slams the door shut, returning an error message instead of the page text. Because this happens at the target server's network firewall layer, it is entirely beyond our control.
