 # `network`
 
-Definiert die IP Adresse bzw. den Host Namen und den Port, auf welchem die Web Oberfläche erreicht werden soll.
+Defines the IP address or hostname and port on which the web interface should be accessed.
 
 **Beispiel**:
 
 ```yaml
 network:
-  # schema is the HTTP schema
-  # setting to `https` does not enable https, it only changes the way URLs are generated
-  schema: http
+  # port is the listening port for UI and api
+  # evcc will listen on all available interfaces
+  port: 7070
   # host is the hostname or IP address
   # if the host name contains a `.local` suffix, the name will be announced on MDNS
   # docker: MDNS announcements don't work. host must be set to the docker host's name.
   host: evcc.local
-  # port is the listening port for UI and api
-  # evcc will listen on all available interfaces
-  port: 7070
+  # externalUrl is the URL you use to access evcc in your browser
+  # used for autodiscovery by the evcc app and by services/devices connecting to evcc
+  # if you're running evcc behind a reverse proxy, use that URL, e.g. "https://evcc.example.com" (note: ensure you add proper authentication)
+  externalUrl: https://evcc.local
 ```
