Contour 2 cable box won't turn back on

I'm a recent cox user, have connected a cox contour 2 cable box, its Ethernet connected and connected to a Samsung Q80 Smart TV, connected to HDMI 4 (ARC).

Every morning I'm having to unplug and plug in the cox contour 2 cable box to work. 

The samsung report hdmi 4 has to signal and has a power on button request for cox cable box. This has no impact, also pressing any button on the contour remote has not impact. The only way to get the cable box to work is to inplug and plug back in.

Any assistance or guidance would be much appreciated.
