Supervisor has no internet connection, but OS does

Hi! For some reason, while trying to install Home Assistant in VirtualBox while following the appropriate documentation, I can’t access the instance from a browser. After running systemctl status docker, I see this:

It says that the supervisor has no internet, even though if I run ping or similar, it says that the host is alive. I’ve tried rebooting multiple times, but nothing has changed. What should I do?

Just as a side note, I’m using Home Assistant OS 6.0, downloaded from, I’m using VirtualBox with KVM Paravirtualization, and I have a Windows 10 host operating system. In addition, networking is working perfectly for other virtual machines.

Check your UFW? is it port 8123 being blocked?
