+> HTTP proxies configured through the `$HTTP_PROXY` environment variable are no
+> longer used for TLS (`https://`) connections. Make sure you also set an `$HTTPS_PROXY`
+> environment variable for handling requests to `https://` URLs.
+>
+> Refer to the [HTTP/HTTPS proxy section](../../config/daemon/systemd.md#httphttps-proxy)
+> to learn how to configure the Docker Daemon to use a proxy server.
