Need urgent help regarding nginx(npm) doh

[Berrus]

I'm running adguard home on docker along with nginx (npm) (also on docker) hosted on vps(linux-Ubuntu 20.xx).

I would like deploy DOH through nginx(npm) but I cannot find a clear solution (noob solution)

-have enabled untrusted doh from adguard config file
-port 443 is taken by nginx, thus doh is hosted on port 444
-also added custom domain(certificate) on both nginx and adguard to enable https

We have an FAQ entry regarding reverse proxies on our Wiki. Does that work for you? If no, what is your Nginx configuration and how do you check the connectivity?

So i tried but didn't work,

On nginx I can access adguard dashboard fine port(3000)

Above image is the config of my nginx on for doh server that is running on adguard. I tried putting thing as mention FAQ in advanced tab of this but could not get working.

When I tried entering the server on AdGuard on ios, it keep giving error invalid upstream.

@Berrus, unfortunately I'm not familiar with any GUI utilities for Nginx configuration. Is the Nginx server on the same machine as AdGuard Home? If so, perhaps try using 127.0.0.1 as the IP address?
