Make Itak work with ATAK via zero tier

Good evening everyone,

I’m actually struggling to see some ITAK phones with other ATAK phones. I’ve been searching all over internet about how and why I can’t see those iPhones on the network via Zero tier. (The ITAK keep showing not connected)

Is there anyone who have any kind of info about that kind of issues ? It would be very much appreciated.

Have a nice day
