Software VPN for IOS Devices
Initial setup | Windows Client | Mac O/S | iOS

Symptoms

The ZeroTier on System Tray shows connected to multiple Network IDs but yet failed to connect.


 

The solution 

Un-check the Network ID that you do not wish to connect.
Only "check" the Network ID you wish to connect.

PS: connect one (1) Network ID at a time to avoid ZeroTier One system confusion.
