If you don’t want HTTPS, you can change <VirtualHost *:443>
to <VirtualHost *:80>
or better consider redirecting all HTTP to HTTPS.
+
+In case you are getting occasional HTTP 504 error messages (“Gateway Timeout”) when accessing the Web UI through your proxy, try adding disablereuse=on to both ProxyPass directives:
+text
+<VirtualHost *:443>
+ [...]
+ ProxyPass /api/websocket ws://localhost:8123/api/websocket disablereuse=on
+ [...]
+ ProxyPass / http://localhost:8123/ disablereuse=on

Multiple Instance
You already have Home Assistant running on http://localhost:8123 and available at home.example.org as describe before. The configuration file for this Home Assistant is available in /home/alice/.homeassistant/configuration.yaml
You want another instance available at https://countryside.example.org
