Hi,
I've recently switched my home assistant instance to a refurbished HP Elitedesk running proxmox. It's all running fine except for that once every few weeks or so it seems to lose it's internet connection making both HA and Proxmox unreachable. The fix at that moment is quite simple, just take out the ethernet cable and plug it back in after a few seconds. I've tried to see if there is a fault logged in proxmox, but can't see where this would be. I did see that the uptime is over 3 weeks, suggesting that proxmox didn't even recognise that it's lost its connection, although this might not be related.
At this moment I don't know where to start looking to find where the problem originates/what to fix. Does anybody have an idea on where I can start?
