Network Issues on Proxmox - NETDEV WATCHDOG transmit queue timed out (e1000e)

[jojd]

Hello everyone,

I’m experiencing a network issue on my Proxmox server and could use some help troubleshooting. The server has been running smoothly for a while, but recently it started losing network connectivity. It works fine for a few minutes after rebooting the router (Unifi router), but then it disconnects again. I've attached a screenshot of the console showing the repeated error messages.

Error Message:​

NETDEV WATCHDOG: enp0s31f6 (e1000e): transmit queue 0 timed out

System Details:​

• Proxmox Version: [8.2.4]
• Router: Unifi router, static IP
