Could not link to Google home neither update firmware

I tried to connect yeelight account to Google home but mi Desk lamp isnt visibile. Firmware update stuck at 40%.German server.
Can somebody help me?Thanks

With the latest policy of Mijia, they don’t allow 3-rd partner control devices with brand Mijia. So you can’t see these devices from google home/Alexa/IFTTT. If you want to control these devices that disappear from google home/Alexa/IFTTT, please try with mihome skill.

Ok, i used the mi home account and not the yeelight, now works perfectly! But the update is still blocked in 40%…

What means blocked in 40%? Can you make a video?
