Yeelight LED Bulb Color v2 get stuck at 25%


I own a Yeelight LED Bulb Color v2 and I have installed the app Yeelight from the apple store.
Every time I try to configure the device with the app it always get stuck at 25 % and after a few second I see a connection failed message.

I have tried diferent server (Germany, EEUU, Singapure) and I have tested with my iPhone 5 and iPad 2.
The ssid / password of my wifi only have letter and numbers.

In any case, whenever it fails, I can see that the device has connected to my wifi, I can see it in the dhcp list and I can ping the device.

Please help !!

Thanks in advance
