I got H200 hub and 4 cameras.Lost all camera and hub access from 2 days.

check my tapo app and it shows me offline.

When i tried to remove all device and add H200 hub it start configuring but when try to connect with camera it shows me failed and i noticed that during pair either hub or camera it self change flash light from slow green to red and green or amber. 
Also, if i skip camera pairing and go to tapo app with only hub pair successfully. The tapo app shows unstable network even my network is good and doesn't show me the hub as well in app.
