Remote Access to Addons with Nabu Casa

Hi there,

Some addons have their own UI that is accessible through a specific port, like the very useful Addon Uptime Kuma that I have been using for some time now. But so far I can only access its UI when I’m on my home network. When I’m remotely accessing my Home Assistant instance and click on the link to open the UI, it tries to open a link like this:

However, this always times out.

I have also tried setting up the UI using the Webpage card and pointing it at the same IP that I use to access the UI locally, but this also times out.

Any ideas on how to make this work?
