Demo not found

Downloaded Android app to try and I get an error that connection to https://demo.opnhab.org:8443 refused…

Is this something I have to configure or is there an error?

Not a great introduction but open HAB looks to be what I need so willing to be perdistent. Also appreciate there’s a lot of volunteer input for which many thanks!

You need to install the demo files, take a look here

It just means demo server was done at that moment, it happens sometimes as it does to any other servers.

Thanks guys, I gave it another go and it seems to be working now: very impressive!
