How do I automatically close a multiplayer room?

I'm trying to test my game's multiplayer features. I set up a text object to tell me if I'm peer or host. Today when testing I kept logging in and being assigned as peer. Is this because I was host at a point in time and didn't disconnect properly and it thinks that there's a host still there?

How do I get the room to automatically close? Do they timeout after a while? Is there a way to ensure I log in as host? Is there a command to clear all active rooms in an instance?

Check your debug event to make sure its accurate?

You can make a quick test by changing the instance name to be sure everything is clear.
