I run a very small bbb server and recently had to replace a router. Once the new router was up and running my public IP changed. I re-ran the bbb-install script and everything seemed good until I tried using firefox to connect. Wouldn't allow audio/video. After some digging I noticed that the public IP in the turnserver.conf was not updated. I changed that by hand, restarted coturn, and firefox was working again with audio/video. Just wanted to pass this along.
