Could not start a new Homey Pro

Bought a pro today. But after creating account I tried to set up the pro. When it showed an orange light, I opened the wifi-setup, I had my wifi-network upper, an beneath the homey setup. tapping homey setup, they switched place and after some time , I got the message no internett connection. I use IOS14.8.1 , and have Apple AirPort Extreme with WPA2, Personal.

Don’t know the exact msg on iOS but on Android you see the same, the mobile detects that there is no internet access connected to the Setup-WiFi of Homey.

Just Continue …

But everything stops there. I t don’t goes futher to the setup I could see in the YouTube video from Homey
