Default [Q] Default Unable to use Google aps after Kitkat upgrade

I received kitkat upgrade via VZ. After the upgrade the phone no longer can use google related apps-youtube, gmail, GV, Groupon when connected on the wifi.

Google apps works via 4g connection. When i tried calling vz they told me to do factory reset. i have tried diff phone for the same apps without issues.

Tried removing wifi and re-adding and uninstalling the apps without luck

Can someone please help me?

My phone model is VS980 4g lte Android 4.4.2
build KOT491.VS98024A
software version VS98024A
