Hi all! I've already got a working Nginx install running, and I'm wishing to expand it to talk to a different service on another internal web server, but I cannot seem to get it to work..

My network config is:

Nginx Server:
Lubuntu 16
Various local web services on various individual ports installed locally
Nginx installed (each current location block points to 127.0.0.1)
IP = 192.168.x.x

Webserver:
Lubuntu 16
One web service running
Nginx is not installed, just the web service
IP = 192.168.x.y

All machines are running on the same subnet and each web service is running on it's own non-conflicting port.
Each machine can access each other happily.
I can access all services across each of the two servers, directly in a web browser, from any internal machine (eg Win10 PC, iPhone etc), including from the servers themselves.

What I assumed I'd need to add to the Nginx config was something like the following:

location /otherwebservice {
proxy_pass http://192.168.x.y:10000; #Example code here
}

But this doesn't work :(

Can anyone help me sort this out please? Or point me in the direction of another post that shows a resolution to this?
Perhaps I need to install Nginx on the 2nd server as well? Or perhaps I need something different than proxy_pass? Or more options as well?

Thanks so much Nginx champs!
