Hi,
I'm using the latest Proxmox on a Ryzen 2700. I've been running two Windows VM's very stable for a long while now. I suddenly noticed I couldn't connect remotely and thought the system had crashed so rebooted. After checking the disk via smartctl, fsck etc. I discovered that its the networking that is dropping out.
If I start one Windows VM, it boots and I can log in but there is no network access in the VM even though Windows reports it is fine. Likewise, Proxmox host itself seems to disconnect from the network and stops responding to pings. I've tried tailling the syslog but nothing useful seems to be appearing.
Even without starting a VM and doing an "apt update" will cause the network to drop out. I lose external access (via ping, ssh and also web).
Any ideas what could be causing this?
