Make sure you have enabled <em>Websockets Supports</em> or similar functionality in your reverse proxy client.<br><br>
If you are getting a <em>400 Bad Request</em> error, find the HomeAssistant log file and look for the following error message:<br>
<code>A request from a reverse proxy was received from 12.34.56.78, but your HTTP integration is not set-up for reverse proxies</code><br><br>

If you are getting a <em>400 Bad Request</em> error, find the
HomeAssistant log file and look for the following error message:<br>
<code>A request from a reverse proxy was received from 12.34.56.78, but
your HTTP integration is not set-up for reverse proxies</code><br><br>
In your <code>configuration.yaml</code> file, add the following lines:<br>

HomeAssistant uses websockets to communicate with the browser.<br><br>
If you are using a reverse proxy, the IP address of the incoming connection is not trusted and gets rejected by HomeAssistant.<br>
