Z-wave door sensor disappeared

I’m trying to get back in to HA after abandoning it a long time ago. Moving from Smartthings. I moved my door sensor over and it was working fine, but now it suddenly disappeared!

I don’t see it in the Z-Wave configuration screen, but I do see this in the log:

Z-Wave entity Unknown Node 14 Sensor (node_id: 14) not ready after 30 seconds, continuing anyway

Is it my sensor?

What does it say in the OZW_Log.txt for node 14?

this is what I see in the log for that:
