After a power outage (tripped circuit breaker) my mini-pc won't connect to the internet or the local network.

I noticed that the RJ45 port on the Minisforum is not lighting up. I tested both the ethernet cable and internet connection, that's not the issue. I also plugged in a RJ45 USB-C dongle and it lit up solid orange but the machine still doesn't have access. Restart does not help.

I am tech savvy enough to have set all this up, but I am not knowledgable in networking or coding. I'm hoping a kind user can help me troubleshoot or point me in the right direction. Is it a driver issue? Is the machine fried? Is it a naming misconfiguration? Firewall? A BIOS setting?

My proxmox GUI was previously accessible from https://192.168.7.94:8006. Thanks for any help.
