First Time Install

I have just installed Home Assistant via this guide Alternative - Home Assistant I have completed the setup using the VirtualBox Linux emulator. Still, when I go to log into the Home Assistant on the app or on my browser using the http://homeassistant.local:8123 URL I keep getting this error:

[supervisor.docker.interface] Can’t install 500 Server Error for http+docker://localhost/v1.43/images/create?tag=2023.10.3& Internal Server Error (“Head “”: dial tcp i/o timeout”)

I have attached a screenshot of what it looks like on my end.

it will try to reinstall every 30 seconds but always fails. does it have something to do with the URL it’s trying to download from as the URL in the script has a colon at the end? When I put the URL in my browser it works without the colon at the very end. You cannot edit the script/URL though, so how can I change this?
