Access specific port on other device?

Tailscale version 1.32.0
Your operating system & version: connecting MacOS 1.32.0 with Linux 1.22.2

I am running a Docker mediawiki server on my NAS that I can connect to on my local network through port 9632, like: 123.123.12.12:9632 . I am trying to connect to it remotely using TailScale, but when I copy the TailScale generated IP and add the 9632 port, it does not load the page - no error either but just doesn’t load. When I connect using just the TailScale generated IP address everything works fine, it directs to the 123.123.12.12 address. I feel like I’m so close to getting this to work - can anyone help?

did you ever get this working? having a similar issue here.
