Cadence Connection issues

Does anyone know how to fix a “no connection” issue with my cadence sensor.
It works for abt 25mins then I get “no connection”.
I’ve tried connecting via ANT+ and Bluetooth, both have same results.
I’m using the Kickr Snap with a tablet. The ANT+ connects via a USB hub (tablet doesn’t have a USB port).
Any help gratefully received.
Thanks
