Installed home-assistant on Debian

Been waiting for 30 minutes and it hasnt loaded

seems to be stuck on the loading page

It will come up once it has downloaded and installed all the needed code bits.
It is downloading these mostly from GitHub and sometimes GitHub can have a little issue.
In the past there were also issues with a throttling limit on GitHub, but that should have been solved in one of the recent releases, so make sure you are installing the absolute newest release.

Maybe RVitals workaround may help:

Edit /etc/hosts and add
140.82.121.34 ghcr.io
185.199.108.154 pkg-containers.githubusercontent.com
etc.
