I tried this since yesterday aswell. The Tdarr Server Logs will tell you that it expected a different Node ID (the name you set). I think this is because even if you change the Node Port in unraids docker template, the config file in /app/configs still sets the Node Port to 8267.
The Problem is, if I change the Port to the same as the Port I set in the template the Server cant contact the Node anymore.
Now I finally got it working by using the "internal docker IPs". Probably not the cleanest way, but it works for me for now.
This is how my templates are looking https://imgur.com/a/nOs1V3P
