Ipfire through reverse proxy

Hi !
during my setup to reach some internal devices from external with ProxyPass in my webserver
(they are wokring well) im a litte bit stcuk with the ipfire…
I set it up like any other device but i get a not found on request… and it seems there is maybe something missing
the setup is

<Location /ipfire/>
	ProxyPass   https://192.168.63.254:444
	ProxyPassReverse https://192.168.63.254:444
	Order allow,deny
	Allow from all
	Require all granted 
</Location>

i get message https://mywebserver/cgi-bin/index.cgi not found

in my working setup (if i surf around the site)

<Location /test/>
	ProxyPass   http://192.168.63.254:9999
	ProxyPassReverse http://192.168.63.254:9999
	Order allow,deny
	Allow from all
	Require all granted 
</Location>

Its working well and when im there i see
https://mywebserver/test/ and the main page
the https in the source is not the problem SSLPrxyEngine is on…

Ciao Gerd
