Repeated ping errors

[gisborne]

MacOS Sonoma M1. I get this over and over in the log:

flutter: logger: RECEIVER: Listening for files...
flutter: logger: PING: Local ping sent
flutter: logger: PING: Local ping error code: 7
flutter: logger: PING: Local ping sent
flutter: logger: SIGNALING: No error or ping received recently, restarting observer...

I've been trying to use flutter_webrtc for some time without success (I can never get a srflx result from ICE). I'm perfectly willing to believe this is something about my setup, but other webrtc apps I run on the same machine work fine.

Note that the downloaded app works, so this may have to do with my Firebase setup.
