Help for activate ADT Security HUB - 2020 (Chile)

Hi guys.
i’m From Chile and this month (11-2020) I bought a ADT Security Hub, when this arrived to Chile, I connected the device to wifi, update version and show the activation code in the screen, but this is not detected in the APP smartthings classic and the new APP smartthings. Today i can’t activate the device :(.

now i know that is discontinued and many problems for ADT smartthing and i’m not so happy but i think in this community can help me to find the way to resolve this problem and activate my ADT security hub.

thank you friends

Use the new ST app, the Classic is deprecated. Check that your hub is connected to the internet and that there’s no firewall blocking any ports.
