Tacx Neo - Not connecting to TDA

Today the trainer does not connect any more via BT to the tacx desktop app.

I tried ANT+ and it said connected, but I cannot see power / speed / cadence data.

Also bottom led light does not work.

Power led and bluetooth light are both on in the trainer.

It is really frustrating. 

I tried also to connect with Tacx utility app but trainer cannot be discovered at all.

Any help?
