Yeelight bulb color not working - timeout response


both of my 2 new lights are not working. After connecting to the light with my phone and then again to the wifi network, I am reaching the 100% and instead to be connected I am getting all the time “timeout error”.

Please consider that with the same phone and wifi network was able to use the same light both 2 years ago.

Could you please help on this, as I can’t use the 2 new lights?

Thanks in advance for your support.
Best Regards,
