GOA is inactive with "no internet connection" message but WiFi is OK
GOA appears inactive (all options grayed out) because it mistakenly says there's no internet connection, see first attached screenshot.
But nonetheless my system has internet connection working ok through WiFi, I can browse web pages and gnome-control-center itself says my WiFi is OK, see second attached screenshot.
My system is Fedora 30.
