Hi everyone,
I’m facing a strange and frustrating issue with my Proxmox setup and could really use some help. Here’s the situation:
• Randomly, Proxmox becomes unreachable via web GUI or SSH, but all the guests are still running and reachable without any issues.
• When this happens, my only “solution” is to blindly type systemctl restart networking (I plug in a USB keyboard since I don’t have a monitor connected). After that, I regain access to the Proxmox web UI and SSH.
• However, all guests are offline after restarting networking, so I have to manually restart them one by one. Once that’s done, everything works fine again—until it happens randomly later.
• If I try rebooting the whole system, even the guests don’t come back online after the reboot.
Clearly, just cronjobbing a networking restart isn’t a viable solution because of the guest downtime.
My Setup:
• Proxmox Version: 8.3.0, non-enterprise repo
• AMD Ryzen 7 5700G
• 64GB RAM
• ASUS ROG Strix B550-F Gaming Mainboard
• NIC: Motherboard’s built-in LAN
• Storage:
• Proxmox installed on a 1TB SSD
• Two RAID1 HDDs (8TB each)
• Additional 1TB HDD
• PSU: Seasonic Prime TX-650
• Almost-new hardware (<4 months old).
I’ve searched around and tried to troubleshoot, but I’m at a loss as to why this is happening. Could it be a driver issue with the NIC? A misconfiguration in Proxmox networking? Something with power management on the NIC or the motherboard?
Any Ideas?
I’d appreciate any help, pointers, or ideas to narrow this down! Let me know if you need any logs or additional details—I’ll do my best to gather them.
Thanks in advance!
