Answer 1

The 'Not Found' error is the standard HTTP 404 Not Found returned by the HTTP server. It generally means the resource you are requesting does not exist.

I got your code to work by changing the resource from "/ws" to "/":

HTTPRequest request(HTTPRequest::HTTP_GET, "/");

and adding the following line

request.set("origin", "http://www.websocket.org");

before creating the new WebSocket. I think it's a header pair that many (or all?) WebSocket servers expect.
