ValueError: Unable to identify Cloudflare IUAM Javascript on website. Cloudflare may have changed their technique, or there may be a bug in the script.

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

URL of the Cloudflare-protected page

https://guidesify.com, https://opinion.guidesify.com This is my site with CloudFlare and using SSL setting: Full (strict) Encrypts end-to-end, but requires a trusted CA or Cloudflare Origin CA certificate on the server. Origin certificate was installed on my server.

All my other sites work and this is the only difference in settings.

Was looking at the Firewall events. It says that the request was challenged because of my firewall rules: Country Unknown states, other entities or organizations

Any idea how I can get past that?

Error was due to Google Cloud Platform's IP addresses being located in the US regardless of where VM location. The workaround I used was to use a dedicated proxy server in my python script.
