Node 2 vs. Bluos 4.0.2

I have a Node 2. I updated to BluOs 4.02 for Win. 
The update took a long time for Node, approx. 20 min.
After the update, BlueOs finds the Node, but 
the Node is not visible in BlueOs.

I have factory reset Node many times, no effect.
I have unplugged the power cord from the wall 
many times, no effect.
I have tried another laptop, no effect.
I've tried a tablet that works fine 
with another room's Node X, still can't find Node.

Node 2 is connected directly to the network.

Did the update break Node 2?
