Last update broke the connection

I had problems with the Mi app, so you recommended the Yeelight app and it worked for couple months. The latest update broke the connection, I still see the lamp connected to router, but i got logged out from my account and my device was removed from the list. Now again I cant connect lamp to the Yeelight app, tried also with Mi app, without luck. I always get connection timed out.
