Your browser is not working with Cloudflare.
It is impossible to pass Cloudflare turnstile.
You can try any site, for example try to open this
BriskBard also is not working

Hi,
I just tested those URLs with the latest CEF4Delphi and also CEF 126 without problems.
Perhaps your IP is banned ?

If your IP is suspicious or it's banned then try using a VPN or an anonymous proxy.

There is no problem with the IP.
It will also be detected even if you change it to a mobile agent. Can you solve this? 126
After changing mobile agent

CEF and WebView2 allow us to embed web browsers in our applications but those browsers have a few unimplemented, missing or disabled features.
Some web pages block embedded browsers and they check those features to differentiate between regular web browsers and embedded browsers. Each web page may check a different set of browser features to do that.
CEF4Delphi and WebView4Delphi are just CEF and WebView2 wrappers. Finding workarounds for a particular web page in a particular application is out of the scope of these projects.
Some developers use the MobileBrowser demo to change some random browser features to see if it works.

It still works with a mobile useragent. Sometimes, depending on the proxy, you need to check the box yourself.
mobile useragent + incognito + proxy mode.
Another thing is that Cloudflare is configured differently on different sites, with different degrees of protection. And the examples given are not the ones you work with)
Cloudflare can..
do not work in incognito mode
do not work through a proxy
one or another api that should be in a normal browser is unavailable
and much more..
Show a real website with a problem and then it will be more visible. All I checked was the normal mode Here in GlobalCEFApp.Chrome Runtime, moreover, should not be a problem.
