Problem with activation Homey Pro

Hi all, i have a problem with activation of my Homey Pro.
During the installation when i insert my passowrd of Wi-Fi (Homey Pro found in the net) i receive this message:
Failed to activate Homey Pro (The access token was not found) and failed the activation.
What this means? What goes wrong? What i check?
Any suggestion?
Cheers, M.

PS: close this, i’ve spent some time on reading the forum and i fouund the solution: using a Android to activate the homey, with the iphone the process doesn’t working.
