@Solla-topee Thanks for the answers 1. All my devices have internet at Home. And they are many. 2. I tried it, nothing changed. 3. Downloaded and installed Tapo again. Same. 4. I followed the advice....

My Tapo app shows suddenly all my devices offline, but not sure that's true as I see indicators lights working and my light bulbs are on. Seems like an app issue. Any ideas how to resolve?
