NIC is down and cannot connect to web GUI

[gsharma]

Hi, this is my first time installing proxmox, i have some linux knowledge but very basic. I have set an ip address and gateway in the setup but the NIC is down and I cannot ping my router or anything on my home network.

This is some of my information, there is no reserved IP address on the router on the one i manually set.

Im just generally very confused.

Compared to the Proxmox manual, you seem to be missing
bridge-stp off bridge-fd 0
at the end of /etc/network/interfaces. I have no idea what could have caused that.

i manually deleted those lines as I did not understand them and i wanted to see if deleting them would help (it didnt) i added them back in just now and still it has no effect on the connection.

DId you reboot the Proxmox? Did you plugin a (known to work) cable into enp0s31f6? Does you router (at 192.168.2.1) detect the cable/connection?

When you run "ip a", do you see LOWER_UP for your physical NIC? If you dont, then there is no carrier signal and its most likely not related to the context of the network configuration file, but rather a cable/nic/port issue as @leesteken already mentioned.

 me0p0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master mgmt state UP group default qlen 1000

This is the solution! I crimped my own cables and I swapped it out for another one (the tester says its fine but regardless i changed it) and it detected the IP for the gateway/router immediatly I did not even have to enter it in during setup! thanks!
