Hi folks – Lately, my home assistant keeps losing network connection for no discernible reason. When it happens, I can’t access the web interface, and from the logs, it looks like HA can’t access any devices on the network either. From what I can tell, enp2s0 fails to renew its IP address.
I have a static IP address for HA in my wifi router, as well as put that same IP address in the web UI settings. All of this was working perfectly fine for a long time, so this issue is only recent (last few weeks).
The only error I see in the logs is for NetworkManager:
Mar 16 18:54:22 homeassistant NetworkManager[456]: <warn> [1742151262.4987] l3cfg[83255319a799acac,ifindex=2]: unable to configure IPv4 route: type unicast 10.0.0.0/24 dev 2 metric 100 mss 0 rt-src rt-kernel scope link pref-src 10.0.0.95
Mar 16 18:54:22 homeassistant NetworkManager[456]: <warn> [1742151262.4988] l3cfg[83255319a799acac,ifindex=2]: unable to configure IPv4 route: type unicast 0.0.0.0/0 via 10.0.0.1 dev 2 metric 20100 mss 0 rt-src dhcp pref-src 10.0.0.95
FWIW, systemctl restart NetworkManager immediately fixes the issue and gets me back on the network.
Any idea how can I go about isolating the problem?
My setup:
- HAOS on VMWare Fusion, with bridged network that connects to my host (Mac OS) wifi (all of which worked perfectly fine up until a few weeks ago).
- Core 2025.3.3
- Supervisor 2025.03.3
- OS 15.0
- Frontend 20250306.0
