I have installed Yeelight Ceiling and was able to turn it on and it worked fine.
Paired it with the remote control and it still worked fine.
After I tried connecting it to the yeelight app (unsuccessfully - the connection always timed out) the lamp started blinking very fast and now I cannot even reset it (5 time turn off and turn on).

Any suggestion what can I do to fix it?
