CEF4 is not working with Cloudflare

Post by madvet »

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 link: https://proxyaz.com/user
BriskBard also is not working

Hi,

I just tested the TinyBrowser2 demo which uses the "Chrome runtime" mode on those sites and it works correctly.
This means that this issue is caused by a missing or unsupported feature of "alloy" CEF browsers.

This also affects other CEF wrappers :

"alloy" - is this feature available only in "Chrome runtime" mode?

I meant that browser in normal mode has this issue.
Browsers in "Chrome runtime" mode are not affected because that mode has many more browser features but it's in experimental state.
