My theory is that home router firewalls vary and give varying results (success or failure) for TURN servers.
Using the test web page:
One of my friends reported:
The server stun:turn.jami.net:3478 returned an error with code=701:
STUN host lookup received error.
The server turn:turn.jami.net:3478?transport=udp returned an error with code=701:
TURN host lookup received error.
Another friend’s tests returned the following:
stun:turn.jami.net
