Default [Q] Could not establish connection, tried everything! Help Required

I was using Android L port. Everything was working fine. Yesterday I installed Panaroid 4.5. I was unable to sign in to my google account and error was Couldn't establish connection.
Then I opted for mobile data connection and sign in was successful.
Issue is Play Store is not working over WiFi. I have tried following things:
Reboot
Factory Reset
Editing Hosts
Deleting Hosts
Using hosts file from Android L Rom

What you guys suggest me? Need HELP!!
