Yeelight filament smart led bulb cannot be reset

Dear anyone who could help,

I have ordered another smart LED filament bulb (I already had one) and wanted to configure it for my system.
However, when I cannot get it in reset mode (using the 5x 2s on 2s off method).
When I turn on the power for the lamp it turns on, when I then turn it off and on the lamp stays off, when I then again turn it off and on the lamp turns on, and so it goes on.
It never goes into blinking mode.

I have tried setting up the miio_default access point but nothing connects to it.

What could I try to get my bulb to work?

Thanks,
Jeroen
