 ⚠️ **Please note:** Look into [this](#adapting-the-sample-web-server-configurations-below) to adapt the above example configuration.
 
 To make the config work you can run the following command:
-`sudo a2enmod rewrite proxy proxy_http proxy_wstunnel ssl headers http2`
+`sudo a2enmod rewrite proxy proxy_http ssl headers http2`
+
+The `upgrade=websocket` parameter requires Apache 2.4.47 or later. On older versions, replace it with the following block, which needs `proxy_wstunnel` enabled additionally:
