Room hosted by Unity Editor cannot be found by build

Options
This always worked before, but inexplicable starting today when I make a build and host a game with my Unity Editor and then JoinRandomRoom or try to get the room list in a build, the game does not show up. I tried this with the PUN2 Asteroids example too just to be sure, and its happening there too. If I host with a build it shows up fine (to another build, but not the Editor).

Any idea what's up with that?
