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:

• [x] I've upgraded cfscrape with pip install -U cfscrape
• [x] I'm using Node version 10 or higher
• [x] The site protection I'm having issues with is from Cloudflare
• [x] I'm not using Tor, a VPN, or an anonymizing proxy
