Cannot Publish or Sub to HiveMQ Broker

[mim212]

I can see that it is able to connect to my HiveMQ Broker running on Hassio from the message on the top bar reading "Reconnected to wss://x.x.x.x:4884" but for some reason cannot successfully subscribe to topics or publish.
HiveMQ is successfully talking to an mqtt-spy instance on the same network, both parties able to publish and receive messages, but the Android MQTT Client is able to do neither?

I have tried with/without SSL, running different ports/ Web Sockets/ Mqtt 3.1 all have the same effect.

Hey, Can you share your broker logs and app logs when you try to subscribe/publish?
