Unraid suddenly stopped working and now can't get IP

I do have an Unraid system that was working fine for about a year. All of a sudden it stopped working and now when I try booting the unit up. I either get the general 169 IP or get the IP address not set and get stuck at the “Tower login”. The systems still boots in the safemode but obviously I can’t see the system on my network.
My system:
Chenbro NR12000 1U 1x 8m QUAD CORE E3-1220 3.1GHz 16GB RAM.
I have tried playing around with the network.cfg file and had no luck so far

Update: apparently somehow the ethernet ports on my Orbi are working bad! If I have anything other than my server plugged in to other ethernet ports, then al of them will stop working. So not sure what happened to the Orbi but that is what I’m working on now,

Can you boot in GUI mode?

I just delete the network.cfg file and let unraid rebuild it during the next start up.

Yes I can get into the GUI mode but still can’t see it in the attached devices

Can you see the network settings in GUI mode?
