You try to use the InvizBox Administration app on your mobile device but are unable to connect.
Connect to your InvizBox 2
Make sure that your mobile device is connected to one of your InvizBox 2's WiFi hotspots (for example "InvizBox 2 VPN" during the initial set up).
If you are connected to your IB2's WiFi hotspot and the app is still not connecting you can try disabling mobile data.
During the initial set up procedure of your InvizBox 2 once you connect to the WiFi hotspot your device may ask if you wish to remain connected to a network which does not have internet access. You should select yes, remain connected.
Disable applications affecting DNS
Some applications (for example AdGuard) change your mobile devices DNS settings. This could cause issues with the InvizBox Administration app. You should disable the application and try to connect using the InvizBox Administration app again.
