Problem/Motivation

My HomeAssistant becomes completely unresponsive via the network after a short while being connected with another device using the Wireguard VPN. The VPN functions for about a minute and then suddenly dies. HA stays unconnected from the network until i pull the power plug and boot it again.

Happens on a RPI3B+ with the latest software installed. Connected via Ethernet cable and has a static IP address assigned in the supervisor.

What could be the issue here? The logs show nothing until it disconnects and after the reboot no logs are to be found.

Expected behavior

Wireguard working without killing the Pi’s network connection.

Actual behavior

The Pi looses it’s network connection and can’t even be pinged any more. The system itself seems to be working when looking at the Pi’s status LEDs and the HMDI-Output. It doesn’t crash completely.
