Unable to connect Yeelight Bulbs to Mi Home app

YEELIGHT LED Bulb (White)
1

Hi All,
Lately, all my 3 Yeelight Bulbs became offline in the Mi Home application.
I tried to reset (by turning it On/Off for 5 times) the bulbs and add them to the application again.
In all cases I got “communication timeout error”.
I’m using 2.4GHz with WPA2 encryption.
I’m using iPhone with IOS 15.6.
Appreciate your help.

P.S tried to connect to Yeelight App as well, same error…
