Question:

Connect Websocket To SSL Server

Dec 15 '15 at 08:54

I'm trying to make a secure connection between a browser and an SSL server, using websocket.

When I connect using the method AcceptNextConnection I get Success but the browser is automatically disconnected after accept, instead of allowing use the socket

I got this from browser (Chorme 47.0.2526.73)

"WebSocket connection to 'wss: //192.168.0.26: 4502 /' failed: WebSocket handshake opening was canceled"

And this from Chilkat log (last release)

If I try to connect from the connect method of the library it works correctly. But I need to use WebSocket for my project and I do not understand what is happening.

I greatly appreciate any help.

Cheers

Websockets is a protocol not implemented yet by Chilkat. See https://tools.ietf.org/html/rfc6455
