Nexus 4, stock 4.3, rooted. WiFi only for data, strong signal
Suddenly today, for no apparent reason, every app requiring access to a Google site stopped working: Google Now gives "Network error" Google Chrome gives "This webpage is not available" for any Google url, but works fine for any other url Android Weather sits on "Updating" Finance gives "Error. Network connection unavailable" Google Maps gives blank screen Play Store gives "Server Error"
The one exception to this is that Firefox can access any Google url, no problem. All other apps accessing the internet work fine.
I have tried rebooting - no effect.
Anyone have any ideas how to solve this problem.
