After changing network I cannot reconnect.

1. Tried to reset on the button and I get the orange blinking and a local WiFi signal is detectable named Tapo_Power_Strip_B280

2. The Android KASA app does not present a choise for P300. If I take the more general (with 2 different devices presented) I get the message "Cannot connect to your smart powerstrip"

3. I have also repeated this priocedure in several different locations in my home.

What can I do?

I have no VPN enabled on the mobile phone.

Help me !
