When i try to navigate to Telegram (https://web.telegram.org) using SimpleBrowser, i get the result below and a blank page is shown. Tried to empty cookies and cache, but no lucky. On regular Chrome the page opens normally.

Any ideas ?

I just tried to open that address from Windows and Linux and I get the "Log in to Telegram by QR Code" page.

Try changing the user agent string, emulating a cell pone, using a proxy or enabling the Chrome runtime mode.

How can i enable the Chrome runtime mode, please ?

The Chrome runtime mode is in experimental mode and many features are not fully implemented but you can try it in the some demos like MiniBrowser.

Open MiniBrowser and add this line in the CreateGlobalCEFApp procedure :

Code: Select all

GlobalCEFApp.ChromeRuntime := True;

Then open that web page. If SimpleBrowser can't open that web page but the modified MiniBrowser demo can open it then this issue is probably caused by some form of browser fingerprinting targeting some feature that's not implemented by default by CEF browsers in normal mode.

The issue was fixed after i tried a different CEF version.
