Does not renew dhcp lease

Running home assistant os in virtual box. Network is bridged to a wi-fi network card. Home assistant has access to Internet for the first 24 hours after restart, then the log is spammed with errors trying to connect to the outside world. “network info” reports “supervisor_internet: false”.

This is a recent version of home assistant, just trying to set it up for the first time.

Curious fact is that network info still reports ipv6 ip address, and I can reach the web app by that address. Not sure what that is caused by. Perhaps ipv6 has longer lease duration?
