Default [Q] Problem Communicating with Google Servers

Just finished installing my first ROM for the GS2. It was the CM 11 ROM, which is working fine however one of the biggest parts of the phone is not working, which is I can not connect to Google.

Whenever I try to go to the play store, youtube, etc, I get this message when I enter my google account details:

"Couldn't sign in

There was a problem communicating with Google servers.

Try again later"

- It has said this for various hours, and I think it's due to a ROM failure but only a few people have mentioned this problem on the thread, and they were ignored.

Thanks, please get back to me as I really do like this ROM.
