I can't make a connection to the MQTT broker at my own server. When I fill in all the fields at the thingstudio connection page and hit the "create connection" button, all fields are cleaned empty. No error messages and no connection is made.. I first thought that it was maybe a browser issue, but Chrome and Firefox show the same results.
My broker is using websockets using TLS, and the MQTT client at HiveMQ does connect to it. So port forwarding and websockets should be correct. (http://www.hivemq.com/demos/websocket-client/)
What could be the problem?
