VeraLite error network

Good morning
I own a VeraLite.
Recently, I no longer have a network connection and the network light is off.
While the blue and orange are steady on.
No modification of the RJ45 cable or even my network.
any idea to find my VeraLite?
Sincerely

Can you ping the VeraLites LAN IP address still ?

Assume you have tried power cycling the VeraLite also?

ping: unreachable
restart: same problem

I tried with RJ45 cable directly on PC; but I can not

The Network light is not lit up at all or flashing ?

The default IP is 192.168.81.1 apparently, if the hub has been reset somehow.

no network light off

ping test without success with factory IP ( 192.168.1.81 )
