Not able to connect on fresh install

[promo123]

To begin with: Sorry for what might be a very novice problem, i appreciate everyone who takes the time out of their day to help me.
I have searched for hours, but seemingly not the identical problem i have in any post i found.

So - i made a fresh install of proxmox and i dont get any network connectivity at all. I can't even ping the gateway.
I controlled the SHA256 checksum, which was good and used balena etcher to create the install medium (kingston 16gb memory stick).
From what i am able to see, things are seemingly configured correct - see images below of cat /etc/network/interfaces and ip a.
The address of 192.168.1.2 is not in the DCHP pool. I've also tried with 192.168.1.200 which is in the DHCP pool, but unused according to arp -a, and still no connectivity. The network card indicates to be alive with a blinking light in the socket.
I can not connect to https://192.168.1.2:8006/ and i can not see it from my pc using arp -a.

I tried alot of various things, but i ended up installing debian 12 just to verify that the hardware was good, and out of the box there was connectivity on a fresh install.

I've also attached the proxmox install process image so that an issue some seems to have had which the interface changing name does not seem to be my case.

If relevant - my system is a Dell Precision 3630 with an intel I219 adapter. The system had Proxmox installed before i bought it, but reset to windows before sale if that could incur some issues for me. It is installed on a m.2 NVME if it matters. I have two of these machines, and i experience identical problems on them.

Thank you for any and all assistance!

Not sure if this is relevant information, but i saw someone ask for results from journalctl -b 0 | grep e1000e.
I dont really know what the results mean, but attached the image.

I also pinged 127.0.0.1 which worked, but i dont know if that really says anything.

I've also tried to install 8.3 now and same issue.

I am not sure wether it is bios, driver or system config. The NIC seems to work fine so i would think it was system issues, though the networking appears fine to me.

Don't know about your network issue but what you should change:

Using 127.0.0.1 as DNS won't work, your pve won't be able to download updates - either use 192.168.1.1 (your gateway) or 1.1.1.1 (cloudflare) or 8.8.8.8 (google) as DNS

pve.home seems to be an already used and registered domain, so don't use that - better use someting like pve.home.internal
.internal is for internal private use (but you can't create official ssl certs for this if you intent something like that in the future)

And for pinging, first try your gateway 192.168.1.1, if that works use some public DNS like 1.1.1.1 or 8.8.8.8, if that works try to ping a domain like google.com.
