IP address (This site can't be reached)

I am having issues when I have set up my Home Assitant When I go to Chrome and try to access Home Assistant, I get “This site can’t be reached”.

I have tried troubleshooting and adding VM VirtualBox to my firewall, but that didn’t work. Any help would be greatly appreciated!

Just to verify, you are trying to get to it at right?

Is this a local connection or through Nabu ?
If local, check if wifi network has changed.
I have had this issue whereby I was able to connect through Nabu but not locally. Then I realized that my Wifi connection had changed from my own Wifi to Comcast’s Xfinity,

Make sure you have the right network defined for your VM.
Some hypervisor networks can be set up with a local-only network.
