HOU Folio Keyboard Bluetooth Connection Issue on iPad Pro 11

I have a HOU folio keyboard for iPad Pro 11” it connected out of the box and was working fine. It suddenly lost connection so did the usual forget device to re-pair it to iPad. But it won’t reconnect iPad Bluetooth just keeps looking (spinning circle) and keyboard is flashing a blue light which should be emitting its bluetooth.

has anyone had this same issue and did they find as fix?
