Google Home Mini won't reconnect

Though not a HA issue (the solution might be …) I suddenly am confronted with 1 of my GH mini’s that wont reconnect to the Wifi. GH is powered, and during daytime the Wifi is off in that section of the House.
Turning it on in the evening scene always made the GH reconnect. As of late, this doesnt happen, (or might but takes really really long, like over half an hour). What I now do is all the plug and reconnect it, and then it simply goes online without an issue.

Does anyone know if Google changed its connection logic lately? Or can we set anything for this in the app maybe?

I do have a spare powerplug I can use to (un)power the GH mini and add to the evening scene in HA, but would prefer to know first if this is expected behavior.

thanks for having a look
