Do you mean this message when you log into myopenhab.org via a web browser?
I’m on OH3, and when I click the link, it takes me to my OH3 overview page as expected. So it sounds like your system is mid-identifying itself. I’m using Chrome on a Windows PC.
Ah, I didn’t realize you were talking about a self-hosted cloud. I recall some discussion about the OH3 cloud being able to identify the client system, but damned if I can find it. May have been on Github.
On the myopenhab cloud, when I click the link I go to https://home.myopenhab.org/. I wonder if there’s an equivalent subdomain that you can directly access on your cloud? Not that this answers your question about anything changing…
