After being using Proxmox (running with proxmox-ve: 8.2.0 (running kernel: 6.8.12-1-pve) / pve-manager: 8.2.4 (running version: 8.2.4/faa83925c9641325)) for almost two years it's not running stable anymore with regars to LXC containers which I'm running. What has changed then? Well, two months ago, I added two UGreen USB-C 2.5G NIC's (eth1 & eth2) to the system but wanted to have them connected just to see if there was short term any issues or something when trying them out. When I finally got around to configure them, it seems that they tend to go offline most likely due to USB auto suspension (another thread on the topic here) and then the vlans for the various NIC's didn't play along initially (another thread on the topic here). So based on the issues with the USB-C NIC's I decided for now to remove them from the equation but still connected to the system and moved over the defined vlans to the primary built-in NIC the system (eth0).
Prior me editing the interface the system been rock stable, but now, well, to so so much. What is causing this behaviour that triggers that I'm not able to access the LCX containers remotely, but no problem from the LXC console within the specific containers. Only way to bring the LXC containers 'online' and accessable again is to reboot the system since systemctl restart networking won't make any difference.
