opening NoVNC in CefSharp Browser

[alipayrow]

Hello.
I'm using the latest version of CefSharp to open a NoVNC page.
I am trying to open NOVNC in cefsharp sample project while I set "IgnoreCertificateErrors = true", but it is not working and the message "Server disconnected (code: 1006)" appears on noVNC page.
It's ok when I try it in a browser [like chrome , firefox , ...] but not works in my application using cefsharp.
[noVNC: is a browser based VNC client implemented using HTML5 Canvas and WebSockets.| https://kanaka.github.io/noVNC | novnc.com]
Does anyone have any Idea to solve the problem?
Thanks
A.P

Does it work in cefclient? Download TestApp from cefbuilds.com, test the same branch as in CefSharp.
