Yeelight doesn’t go beyond 25% when trying to add device

I have been using my yeelight Led buld for a year but suddenly it stopped connecting/ showing offline. So I delete the device and try to readd the device to my app but it’s stops at 25% every time. So I thought the bulb was bad so I ordered a new one and it was still same problem

Did you get any message after the connection failed?

Have you ever upgraded your APP or device firmware.

It says connection failed

My apps are on auto update and my firmware says everything is up to date
