Yeelight LED Strip: Unavailable after some time

Hi, all
i am wondering if anyone having issues with the xiaomi light strips.
It works fine for the most part, except that it goes unavailable after some time (once every 2 days?)

It happens randomly, the device does not seem to be disconnected whatsoever

I can still control it fine through the app. To fix it i had to turn off (remove power) from the light strip and turning it back on manually

Any ideas what is causing this? Thank you in advance!
