+1. Make sure your network has internet access.
+     - During first startup, time will be synchronized. Ensure NTP is allowed in your network.
+     - During first startup, Home Assistant completes the installation. It needs access to the following URLs:
+       - version.home-assistant.io: to fetch new version information.
+       - github.com: to update metadata of the add-on store.
+       - ghcr.io: the GitHub container registry to fetch new Home Assistant updates.
+2. After changing your network environment, wait a few minutes. Home Assistant will try to reconnect.
