MQTT not subscribing after subscribe failure

I (25347204) MQTT Client: Not subscribed, discarding message.

Maybe make MQTT re-subscribe every time message comes in and MQTT is connected, but not subscribed.
Or or remove that check entirely since its buffered internally.
But still need to know when its not subscribed and connected. Timer maybe ?
