## Root Cause

Cloudflare's Browser Integrity Check or custom WAF rule blocks requests based on the browser's TLS fingerprint or User-Agent, often triggered by automated tools or outdated browsers.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| Cloudflare WAF 2023-10-01 | active | — | — |
| Cloudflare Browser Integrity Check | active | — | — |
| curl 8.0.0 | active | — | — |
| Python requests 2.31.0 | active | — | — |

## Workarounds

1. **Update the browser or tool to a modern version with a common TLS fingerprint. For curl, use a modern version (7.88+) and mimic a real browser: curl -A "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36" https://example.com** (85% success)
   ```

   ```
2. **If accessing programmatically, use a headless browser like Puppeteer with a realistic User-Agent and TLS settings: const browser = await puppeteer.launch({ args: ['--no-sandbox'] }); const page = await browser.newPage(); await page.setUserAgent('Mozilla/5.0...'); await page.goto('https://example.com');** (80% success)

3. **Contact the website owner to have your IP or User-Agent whitelisted in Cloudflare's WAF, or ask them to disable Browser Integrity Check for specific paths.** (75% success)

## Dead Ends

- **** — Browser Integrity Check often requires JavaScript to pass; disabling it may trigger additional blocks. (80% fail)
- **** — Error 1010 is based on browser signature, not IP; changing IP alone won't help unless the browser fingerprint also changes. (70% fail)
- **** — The block is deterministic; retrying with the same signature will always fail. (100% fail)
