I need help using reverseproxy in combination with hestia

Hello, maybe someone can help me here.
Following issue i would like to use a reverseproxy for my domain wich i have addet to hestia.

Lets say my domain is test.com my files will be located after adding it to hestia here:

I did the reverseproxy setup like this on another ubuntu 22.04 server the reverse proxy is working but the big problem what i have is that my domain wich is pointed to the reverseproxy ip and not hestia backend shows me not the website wich is located here /home/Forum/web/test.com/public_html

It seems like i just see the index.html file wich is located on my hestia server here /var/www/html

Maybe someone can help me to fix the issue and setup the reverse proxy right to get a mirror for the right dictionary /home/Forum/web/test.com/public_html
