Cannot get the nginx sorted out for the production environment

I’ve got corteza on ubuntu 22.04 with the latest docker and compose - everything appears to be running swimmingly.

I have the containers on the same network.

Where i’m getting lost, when i attempt to reach the ip address of the server hosting corteza, i cannot get the instance to roll over to the application, as if the forward is not working.

any suggestions on where to poke?
