Routing breakdown

I have two z-wave devices that started having problems over the weekend and should not share mesh infrastructure until the hub. One is a hardwired Mimolite that logging says is “not responding to polls” and “failed to update mesh info”. The second is a Ring keypad that won’t connect unless I move it. Both devices are each routing past at least 2 devices that are meant to improve the mesh. The system solidly functioned for weeks up until now.
