Room closing after inactivity

Running Jitsi self-hosted in Unraid. I use it for one on one music lessons. My new instance has been working great, with one exception. When I arrive to my studio, I start up the room, authenticate, turn on lobby, then minimize the window. That way it’s ready for the student whenever they are. So I might start it at 3:30, but not see another participant until 5. But I’ll check every 30 minutes and it’ll be back on the welcome screen. Is there a single participant timer that closes the room? I’d like to disable that, if possible.

No, so long as there’s at least one participant in the room, it stays open.

Strange that this happens then. A minor quirk in my setup probably. I have no issues with the meetings.
