Created attachment 36527 [details] example configuration Since this change introduced in httpd-2.4.39, SSLProxy-Settings defined inside the <Proxy> section are no longer applied for http-healthchecks. https://github.com/apache/httpd/commit/0dcd178c561f3293775a3d5953c764d64a5af233 I have tested it with SSLProxyProtocol - directive. As soon as i move the directive up in the virtual server context, they are applied correctly. I assume that other SSLProxy*-direcrives are affected too, because of the newly introduced reset/reinit of the dir_config. See attached configuration for details.
