Help needed to configure Waf2Py properly

[AppLEaDaY]

I installed the software correctly, though now I see quite a lot depends on my deduction.
The scenario where I might want to use Waf2Py is made of a nginx server working as a proxy for Docker containers.
So the application should be the name for the nginx virtual host, Listens to should be the public IP address bound to that name and Real web server should be the IP address of the container where the nginx virtual host would forward the requests to: is this correct?
I had a look at the Expert Configuration tab, but in the Nginx configuration section I find hard to interpret the proxy_pass line.
Anyway I clicked on the Enable application button, but the status of the website stays Disabled.
What am I missing?

Thanks in advance!

yes, "Listen to" is the public address and the container address in "Real Application IPs". That need to configured under "HTTP/HTTPS" tab. Then press the "play" button and the app will be enabled.

I press the play buttons, but every "app" I configured there stays disabled.
Actually I have no real container listening behind nginx, but I expect nginx virtual hosts could be enabled anyway.
How can I debug what's happening, or what is not happening?
Thanks in advance!
