Before creating an issue, first upgrade cfscrape with pip install -U cfscrape
and see if you're still experiencing the problem. Please also confirm your Node version (node --version
or nodejs --version
) is version 10 or higher.
Make sure the website you're having issues with is actually using anti-bot protection by Cloudflare and not a competitor like Imperva Incapsula or Sucuri. And if you're using an anonymizing proxy, a VPN, or Tor, Cloudflare often flags those IPs and may block you or present you with a captcha as a result.
Please confirm the following statements and check the boxes before creating an issue:
- I've upgraded cfscrape with
pip install -U cfscrape
- I'm using Node version 10 or higher
- The site protection I'm having issues with is from Cloudflare
- I'm not using Tor, a VPN, or an anonymizing proxy
