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:

Python version number

Run python --version and paste the output below:

Python 3.6.10 :: Anaconda, Inc.

cfscrape version number

Run pip show cfscrape and paste the output below:
