Does anyone else have this issue?
It doesn’t work on my PC or on my phone. Also trying to access it with mobile data doesn’t help.
According to status.openhab.org the demo systems are online
Update: I noticed that the demo servers only reject the connection when using http and not https.
So https://demo.openhab.org/ works and http://demo.openhab.org/. So it seems like the Redirection from http to https doesn’t work.
