Sent non-empty 'Sec-WebSocket-Protocol' header but no response was received

I'm using the Paho MQTT-Client with Apache Cordova to Connect to the Moquette MQTT-Broker in Java.

I'm working on this project for for a while now and now I am trying to connect via the "wss" protocol with an self signed certificate.

With the Client running in the Browser everything works as expected. But running on the Android Emulator I'm getting this error: "WebSocket connection to 'wss://10.10.10.154:8083/' failed: Error during WebSocket handshake: Sent non-empty 'Sec-WebSocket-Protocol' header but no response was received", source: file:///android_asset/www/plugins/cordova-plugin-websocket/www/websocket.js (162) While investigating I found this issue with moquette https://github.com/andsel/moquette/issues/90

So I tried changing the Line this.socket = new WebSocket(wsurl, ["mqtt"]); to this.socket = new WebSocket(wsurl, ["mqttv3.1.1"]);

Now it works as expected in the Browser and in Cordova with Android. I am not shure, if this would be a valid change, if the Problem is the Moquette MQTT Broker or the if the Paho Client is responsible.
