Hue bridge integration broken suddenly and not coming back

Hi,

I lost control of Hue bridge connected lights through ST.
and it is not working yet.
Has anyone else noticed same behaviour ?

is it only me or everyone ?

after a resync of the hue connect app, it is working again.
weird. why did it get broken ?
I had not noticed anything similar in the last 2 years with Hue and ST.
