Hi All,

hope you're all well. I'm quite new with NGINX and have recently implemented and NGINX with Nextcloud which was successful.
Both of these were installed within docker containers.
I'm now trying to utilise NGINX more for other applications that I have such has Home Assistant (HA).
My HA lives on a different host which has my home subnet IP (192.168.2.131)
My NGINX lives on a host with ip of 192.168.2.85 but it obviously has container's IPs set automatically by docker.
If I jump into /bin/bash of NGINX prompt, I am able to ping my HA box, but not the other way around for obvious reasons.
I've set up proxy host pointing to my HA box (as per attached screenshots)
However, from reading some article, I should at least see in HA log if any traffic is trying to hit it from NGINX but I'm not seeing it.

I'm wondering if anyone can please shed any light here? Cheers
