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>
<pre style="text-align:left;">
http:<br>
use_x_forwarded_for: true<br>
trusted_proxies:<br>
- 12.34.56.78 # The IP address from the error message
</pre>
