Connection failure Zwift hub one

Ok, not sure where to start, originally was connecting via bluetooth via windows but was getting connection issues. So bought and ANT + with docking station so i can place by the back of the hub and still getting connection failure. Sometimes the pedals just spin and there is no resistance, sometimes i get resistance and it then cuts out during ride on a number of occasions.

Tried just via bluetooth, on my Android device, same problem…

Losing faith, so frustrating.

Please help
