Bonjour Issue with iOS Update 3.0.18
iOS v3.0.18 has introduced an issue with Bonjour automatic connections. This means any iOS device using the automatic Bonjour method of connecting will “time out”.
The work-around will be to use Direct Connection.
From the login screen, select Direct Connection instead of Bonjour.
Click on Settings.
Enter the local IP address of the Mac computer that’s running the Unity Server in the first field - Main IP/Host address. Then click back.
This is actually a far more robust way of connecting, there is no need to go back to the Bonjour method after this is fixed in the app.
