After reinstalation WiFi - "lost connection to the Indoor Air Quality Sensor"

After reinstalling WiFi (I have 2.4GHz, of course I tried turning off the second 5 GHz band) during reinstallation it reports (with a blue flashing light) after finding the Netatmo device and clicking on it: "ERROR, we are sorry, but we have lost connection to the Indoor Air Quality Sensor. This installation will restart". Nothing helped and I can't even look at the Wifi settings. Because of this, I have already changed the wifi name and password, home names, etc. and still nothing helped. oh yeah ... Please help me,Please help me, Please help me ...
