paho mqttws31.min.js is not connecting with ssl on

[hz2018tv]

it connects fine without ssl turned on both broker and sub sides. but with ssl turned on both side, getting "opening handshake canceled". debugger inside chrome shows it stops at
if (this.connectOptions.mqttVersion < 4) {
this.socket = new WebSocket(wsurl, ["mqttv3.1"]);
} else {
this.socket = new WebSocket(wsurl, ["mqtt"]);
}
I am not sure why the same code works with ssl off, if it is a version issue. so I guess it is not.

anyone succeeded in using paho mqtt3.1.min.js with latest hbmqtt broker? pls help.
