Thanks for your post on our Community Forums @rilej, and a very warm welcome to you!
Sorry to hear of the issues you've been experiencing, is this happening on multiple set top boxes, or just one in particular?
If this is just on one box, it may be worth switching the boxes over to see if the fault follows the set top box, or if it remains at the outlet of the effected set top box.
I've attempted to run a flow on your equipment and it appears that this is unreachable - which tells me it's switched off. Do you leave your set top box in standby mode, or is this powered off completely?
