maybe it has some thing to do with
v1:1 Blocked script execution in 'about:blank' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.

Some web pages detect embedded browsers. Perhaps cloudflare is doing that.

The link is not about cloudflare?

That website seems to be using the Cloudflare services and the error you posted mentions them : I just tested that URL with the latest BriskBard version. I click the "View PDF" link, it passed the human test and I could see the PDF in a new tab.

The "human" tests may fail for many reasons:

• Blacklisted IP.
• Using a CEF browser with some unusual configuration.
• etc.

Thank you for your help! May it was the language setting!

I'm facing the same issue now. Did it work for you eventually? If yes, then what helped?

try that website with the current demos and compare the settings with your application.
Compare the command line switches when you navigate to chrome://version

How can I change CEF's command line swithces in my application?

The command line switches are added automatically when the application sets GlobalCEFApp properties.

Compare the GlobalCEFApp properties between the working demo and your application.
