Proxmox disable NIC after some period of time?

[kolbycheesey]

Fresh install of Proxmox (version 8.3.5) on a Dell T620 with 256 GB of Memory on a 1TB SSD. Boot sequence is great and I am able to reach the Proxmox web GUI, but after some amount of time initially it was 30ish minutes now it seems to get to about 6-12 hrs then the ethernet connection is disabled from within proxmox. I ran an initial update once the proxmox was installed, I am trying to find what would be causing it but my syslog never reports anything crazy happening it just disconnects. If anyone has any ideas or suggestions that would be awesome.

It works for a period of time by running the systemctl restart networking but long term this seems unrealistic to continually have to do to make sure everything is on the network. I have attched the logs from a previous disable, the cat /etc/network/interfaces, the cat /etc/hosts, and ip-a

Solved: (possibly)
A net-tools update seems to have maybe fixed this issue as it has been up for over 24 hours now without any trouble. This did not solve it, it seems as if after i run a systemctl restart networking I don't seem to get the issue any more only on total reboot. So my guess now is to chase down the difference in what happens on restarting the networking vs server reboot.

This was also wrong it just died again after running the restart here is the dmesg | grep eno1

Was able to get a little bit more information from cat /var/log/ifupdown2/ around the time it would have went down and got debugout.txt

Solved, in my infinite wisdom I changed the DNS Server to 8.8.8.8 and changing it back to my local resolved my issues.
