In the near future (optional) encryption and authentication will be added for the LAN services, see https://github.com/victronenergy/venus/issues/1255. Both will be handled by the webserver (nginx). In order to make at least authentication work, the venus-html5-app should no longer connect directly to the MQTT websocket, but through the webserver instead. The url is http://[host]/websocket-mqtt or https://[host]/websocket-mqtt.
The current Venus releases already include mentioned path. Accessing the app over https:// will redirect to http:// at the moment.
