    Description

      At the moment if you access any cloudflare or akamai protected website with latest webengine Nanobrowser, you webengine is detected as bot hence rejected without even asking to complete a captcha.

      Also other social platform like whatsapp web do not work.
      You can check the below websites:
      https://dash.cloudflare.com/login
      [https://en.aw-lab.com/
      ] [https://web.whatsapp.com/

      Considering the spread that the new Cloudflare Turnstile will have this is a critical problem.

      Seems like Webengine is not properly presenting himself as a browser and do not reply well enough to antibot challenges to pass the tests

      To check the Headers and other information trasmitted by Webengine I would suggest:
