Second Z Wave Hub detached building

I am extremely new to HA but I will try and explain my best. I am running HA on a RPI5 in our house with a Zooz 800 installed using the Z Wave JS UI add on. We a couple of other buildings on our property that are all on the same network via wired ethernet. I installed a second Zooz 800 on a second RPI5 in a docker container.

I have followed every tutorial I can find and it seems as they all say come back to HA and add a second hub via Z Wave JS and uncheck Use Z Wave Supervisor Add On. When I input the ip of the container and port 3000 I get an error of failed to connect. I have fought this for days trying to make any changes I can find and nothing seems to change things. Any help at all would be much appreciated.

You need to turn on the HA Websocket in ZUI settings. Also depending on how you are running ZUI, you may need to expose ports (usually 3000) in Docker.

Websocket was turned on in settings. Not sure about port 3000 being exposed in Docker. How would I go about figuring that out?

You define that when you deploy the container.
