[Q] google play store connection error

[blueraheel]

Hi, I'm running CyanogenMod 10.1 nightly on my sgh-i777. Everything was working perfectly but now Google play store is not connecting and is only giving the option to retry. The Google account is also not syncing. Internet is working fine through the browser and other apps.
Note: when I open play store a notification pops up "sign into wifi network".
I've tried clearing app data and cache. Tried reflashing gapps. Tried rebooting the phone. Tried dipping the phone in holy water , nothing.
Plz help

i removed the google account and re added it , it says
"couldn't sign in. Cant establish a reliable connection to the server. This could be a temporary problem or your android device may not be provisioned for data services .IF it continues , call customer care. "
even though my phone is connected to wifi.
what is that notification about signing into wifi network? it didnt appeared before but it started appearing when this connection error started.
