Hi, I am struggling with a new issue on my Proxmox node recently. A quick summary, every 1-3 days, overnight, my Proxmox host and all of it's LXCs and VMs will become inaccessible by the WebUI or SSH. The machine is powered on however. I am trying to find the proper logs that would help me investigate this issue deeply so that I can discover and resolve the cause.

---

I have a feeling that it might be related to the recent Proxmox update. I am currently running Proxmox VE 8.4.1. I updated about a week ago from Proxmox VE 8.3.X and this issue had never happened to me across 6 months of usage.

I've already tried searching online for logs. I went via SFTP to /var/log/ and I see a number of files and folders. I do not have a var/log/sysloghowever, which I saw was a suggestion on another forum.

Currently I have journalctl -f running via a monitor connected to the Proxmox machine in hopes that if the freeze happens again I can check to see if the log is still live-updating and/or what it last shows. Although I get a feeling that this is not an ideal solution.

Any suggestions or help would be greatly appreciated! I depend on some of my containers running 24/7, so I hope to get this resolved asap. Thanks

I made a reddit post here and got some useful replies. I've tried editing my Interfaces file to workaround a potential Intel e1000e driver issue. This thread may no longer be needed if I am successful.
