Can not connect with secure websocket server from chrome application

Hi Team, we have a product is using boost library to implement secure websocket server . Now we want to use QtWebsocket to implement secure websocket server for new version of product. But we got some errors with QtWebsocket.

Currently, we use a self signed root ca to sign for a local certificate which we use for websocket server. you can see example in here .
This way works very well in v1 of our product.

But when we change to use QtWebsocket, client app can not connect with websocket server.
Need to have an extra step for user before client app can connect with server.

after this step client app can connect with server

I also see some differences between boost library and Qt library.
In the keychain:

• use boost library: I don't see the certificate with name "localhost"
• user Qt library: I always see the certificate with name "localhost. Even I deleted it, it will appears again.
