HA disconnects from everything after unplugging ethernet and never comes back until host computer reboot

Dear HA community,

I have HA running in Oracle Virtual Box. After some recent experimentations where I needed to unplug ethernet from the computer, after plugging it again and network being working find on host OS, the HA loses connection to everything and never recovers it, even after restarting HA and even rebooting the VM. Only after host PC (Windows 11) restart everything returns to normal.

Is it expected behavior? Any workarounds?

Sounds like a Virtual Box issue to me.

it could be, but since virtual box wasn’t updated but HA was… I would hypothesize that it is more likely HA issue. But I’ll continue trying to find solution, I was just hoping someone else could share experience with the same situation. Knowing that in another similar setup (HA on Virtual Box) disconnecting and reconnecting the ethernet wire doesn’t cause similar issue.
