Turn server
An ICE connection will be used when generating an autoQR connection over the internet or when setting ICE when manually specifying a connection
When Interactive Connectivity Establishment (ICE) fails to form a direct connection between two instance of Juggluco, a turn server can be used to relay between them.
In this screen, you can specify such a turn server. When you don’t specify anything, some default servers are used, but they could possibly not handle all traffic and are restricted in the total amount of traffic allowed. So to be certain of a fast and reliable connection, you can better specify another Turn server.
