Ubuntu Server 22 network connectivity

[Fitz135]

Hello Proxmox community and thank you in advance. This is my first time posting so let me know if i missed any pertinent information, I built a ubuntu 22.04.4 server and was able to update/upgrade. Once I come back to it after a couple days I am no longer able to connect to the internet or ping from other system on the same LAN. I can ping my PM host but not the VM. The first time this happened I assumed i messed something up with the config after troubleshooting for a few hours. Since it was a vm i cut my losses and rebuilt. Same thing happened... I was able to install update/upgrade and came back a few days later and no longer able to ssh to it or update upgrade again. I have rebooted it a few times. Any help will be appreciated.

Thank you!

Hey,

could you post the VM config(qm config <VMID>) and the output of ip a from inside the VM. How did the VM get its IP, is it statically assigned or do you have a DHCP handing out IPs?
