cfscrape not working on this particular site

[musama95]

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

Got the same problem on https://bitcointalk.org/index.php?topic=5215051.0;all. CF had changed their js script. Now it's not included into html page, but it's loaded by another script:

var cpo = document.createElement('script');
      cpo.type = 'text/javascript';
      cpo.src = "/cdn-cgi/challenge-platform/orchestrate/jsch/v1";   <--- HERE
      var done = false;
      cpo.onload = cpo.onreadystatechange = function() {
        if (!done && (!this.readyState || this.readyState === "loaded" || this.readyState === "complete")) {
          done = true;
          cpo.onload = cpo.onreadystatechange = null;
          window._cf_chl_enter()
        }
      };
      document.getElementsByTagName('head')[0].appendChild(cpo);

Can this problem be fixed or is it impossible to fix? I don't understand how cloudflare works and I have a very rudimentary knowledge of Js so I'm not sure what the code you wrote does @slo-Oth
